Check Digit Verification of cas no

The CAS Registry Mumber 353476-50-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,5,3,4,7 and 6 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 353476-50:
(8*3)+(7*5)+(6*3)+(5*4)+(4*7)+(3*6)+(2*5)+(1*0)=153
153 % 10 = 3
So 353476-50-3 is a valid CAS Registry Number.

Synthesis of 2,3,4-trisubstituted pyrroles via a facile reaction of vinyl azides and tosylmethyl isocyanide

Chen, Wenteng,Shao, Jiaan,Li, Zhi,Giulianotti, Marc A.,Yu, Yongping

body text, p. 214 - 221 (2012/03/07)

A facile synthesis of polysubstituted pyrroles from tosylmethyl isocyanide (TOSMIC) and readily synthesized vinyl azides was developed. The reaction proceeded under mild conditions in the presence of base. 2-Tosyl-substituted pyrroles were obtained in moderate to good isolated yields. Additionally, a base-initiated one-pot pyrrole synthesis also was developed using carboxaldehydes, ethyl 2-azidoacetate, and TOSMIC.
