Check Digit Verification of cas no

The CAS Registry Mumber 55064-98-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,5,0,6 and 4 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 55064-98:
(7*5)+(6*5)+(5*0)+(4*6)+(3*4)+(2*9)+(1*8)=127
127 % 10 = 7
So 55064-98-7 is a valid CAS Registry Number.

Atom-efficient gold(I)-chloride-catalyzed synthesis of α-sulfenylated carbonyl compounds from propargylic alcohols and aryl thiols: Substrate scope and experimental and theoretical mechanistic investigation

Biswas, Srijit,Dahlstrand, Christian,Watile, Rahul A.,Kalek, Marcin,Himo, Fahmi,Samec, Joseph S. M.

supporting information, p. 17939 - 17950 (2014/01/17)

Gold(I)-chloride-catalyzed synthesis of α-sulfenylated carbonyl compounds from propargylic alcohols and aryl thiols showed a wide substrate scope with respect to both propargylic alcohols and aryl thiols. Primary and secondary aromatic propargylic alcohol

An aqueous and recyclable copper(i)-catalyzed route to α-sulfenylated carbonyl compounds from propargylic alcohols and aryl thiols

Watile, Rahul A.,Biswas, Srijit,Samec, Joseph S. M.

supporting information, p. 3176 - 3179 (2013/11/06)

A highly efficient one-step copper(i)-catalyzed method for the synthesis of α-sulfenylated carbonyl compounds from propargylic alcohols and aryl thiols in aqueous media is described. A variety of α-sulfenylated carbonyl compounds can be synthesized in good to excellent yields. The catalyst has been successfully recycled up to 4 times without any loss of activity in an aqueous medium.

-

Page/Page column 13, (2013/08/15)

The present relates to a method and a kit to produce an optically pure α-sulfenylated carbonyl compound comprising a primary or a secondary propargylic alcohol and an aryl thiol, a transition metal catalyst and a solvent.

A gold(I)-catalyzed route to α-sulfenylated carbonyl compounds from propargylic alcohols and aryl thiols

Biswas, Srijit,Samec, Joseph S. M.

supporting information; experimental part, p. 6586 - 6588 (2012/07/28)

A one-step atom efficient gold(i)-catalyzed route to α-sulfenylated ketones and aldehydes from propargylic alcohols and aryl thiols is described.

A Novel Synthesis of 3,4-Dihydro-2H-1-benzothiopyrans. Acid-Catalyzed Intermolecular Cycloaddition of Acetylenic Alcohols with Arenethiols

Ishino, Yoshio,Masaoka, Toshihiro,Hirashima, Tsuneaki

, p. 1185 - 1188 (2007/10/02)

Reaction of the acetylenic alcohols with arenethiols in the presence of p-toluenesulfonic acid (p-TsOH) gave 3,4-dihydro-2H-1-benzothiopyrans (thiochromans) in good to excellent yields, the reaction of which may involve intermolecular cycloaddition via ca
