Check Digit Verification of cas no

The CAS Registry Mumber 1240982-91-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,4,0,9,8 and 2 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1240982-91:
(9*1)+(8*2)+(7*4)+(6*0)+(5*9)+(4*8)+(3*2)+(2*9)+(1*1)=155
155 % 10 = 5
So 1240982-91-5 is a valid CAS Registry Number.

Domino approach for the synthesis of pyrrolo[1,2-α]pyrazine from vinyl azides

Chen, Wenteng,Hu, Miao,Wu, Jianwei,Zou, Hongbin,Yu, Yongping

supporting information; experimental part, p. 3863 - 3865 (2010/11/05)

A domino synthesis of pyrrolo[1,2-α]pyrazine from 1H-2-pyrrolecarbaldehyde and readily synthesized vinyl azides was developed. This reaction proceeded under relatively mild conditions in the presence of base. Additionally, a possible mechanism for the entire sequence is proposed.
