50652-79-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 50652-79-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,0,6,5 and 2 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 50652-79:
(7*5)+(6*0)+(5*6)+(4*5)+(3*2)+(2*7)+(1*9)=114
114 % 10 = 4
So 50652-79-4 is a valid CAS Registry Number.

-

Page/Page column 13, (2010/02/12)

[PROBLEM TO BE SOLVED]: To provide a new fragrance and flavor element which have high acceptability, excel in odorant, flavor, depth, etc., and can be useful as a flavor seasoning substance for various products effectively, and to provide a fragrance and a flavor composition containing the same. [SOLUTION]: The tertiary mercaptoketone shown by following formula(I): [Wherein, R and R' are the same or different C1-C3 alkyl group; and the total carbon number of R and R' is 3 or 4], the method for producing the compound, and the fragrance and flavor composition containing the compound.

Reaction of Diketene with Grignard Reagents in the Presence of Cobalt Catalyst. A Convenient Method for the Synthesis of 3-Methylenealkanoic Acids Leading to Terpenoids

Fujisawa, Tamotsu,Sato, Toshio,Gotoh, Yoshihiko,Kawashima, Masatoshi,Kawara, Tatsuo

, p. 3555 - 3559 (2007/10/02)

Primary alkyl Grignard reagents react regioselectively with diketene in the presence of cobalt(II) iodide to afford 3-methylenealkanoic acids in good yields.The synthetic utility of this reaction is demonstrated in the syntheses of terpenoids by two methods.Utilizing the isomerization of double bond of 3-methylenealkanoic acids, geranic acid and farnesic acid were obtained in two steps.Another method, the tandem sigmatropic rearrangement of the corresponding allylic esters was used for the synthesis of C18-Cecropia juvenile hormone.
