Check Digit Verification of cas no

The CAS Registry Mumber 1206626-34-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,0,6,6,2 and 6 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1206626-34:
(9*1)+(8*2)+(7*0)+(6*6)+(5*6)+(4*2)+(3*6)+(2*3)+(1*4)=127
127 % 10 = 7
So 1206626-34-7 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.
