Check Digit Verification of cas no

The CAS Registry Mumber 70380-70-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,0,3,8 and 0 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 70380-70:
110 % 10 = 0
So 70380-70-0 is a valid CAS Registry Number.

A One-Pot Tandem Approach for the Synthesis of 5-(Het)aryloxazoles from Substituted (Het)aryl Methyl Alcohols and Benzyl Bromides

Vinay Kumar, Koravangala S.,Swaroop, Toreshettahally R.,Rajeev, Narasimhamurthy,Vinayaka, Ajjampura C.,Lingaraju, Gejjalagere S.,Rangappa, Kanchugarakoppal S.,Sadashiva, Maralinganadoddi P.

supporting information, p. 1363 - 1366 (2016/06/01)

A new modified van Leusen strategy has been developed for the synthesis of biologically significant 5-substituted oxazoles by the reaction of (het)aryl methyl alcohols or benzyl bromides as precursors with tosylmethylisocyanide (TosMIC) under basic conditions. This method is efficient, takes place under mild reaction conditions, and is tolerant of various functional groups with high yield.

Cobalt-catalyzed addition of azoles to alkynes

Ding, Zhenhua,Yoshikai, Naohiko

supporting information; experimental part, p. 4180 - 4183 (2010/11/19)

A ternary catalytic system consisting of a cobalt salt, a diphosphine ligand, and a Grignard reagent promotes syn-addition of an azole C(2)-H bond across an unactivated internal alkyne with high chemo-, regio-, and stereoselectivities under mild conditions. Mechanistic experiments suggest that the reaction involves oxidative addition of the oxazolyl C-H bond to the cobalt center, alkyne insertion into the Co-H bond, and reductive elimination of the resulting diorganocobalt species.

Heterocyclizations via TosMIC-based multicomponent reactions: A new approach to one-pot facile synthesis of substituted quinoxaline derivatives

Neochoritis, Constantinos,Stephanidou-Stephanatou, Julia,Tsoleridis, Constantinos A.

scheme or table, p. 302 - 305 (2009/06/23)

A novel multicomponent reaction involving o-phenylenediamines, aldehydes and p-toluenesulfonylmethyl isocyanide (TosMIC) in the presence of a base leading to the formation of quinoxalines in very good yields is described. Georg Thieme Verlag Stuttgart.
