Check Digit Verification of cas no

The CAS Registry Mumber 143850-05-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,3,8,5 and 0 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 143850-05:
(8*1)+(7*4)+(6*3)+(5*8)+(4*5)+(3*0)+(2*0)+(1*5)=119
119 % 10 = 9
So 143850-05-9 is a valid CAS Registry Number.

Generation and cycloaddition reactions of the 1,2,3-triazole analogue of o-quinodimethane

Mertzanos, George E.

, p. 4499 - 4502 (1992)

4,5-Dihydro-4,5-dimethylene-1-phenyl-1,2,3-triazole (4), the 1,2,3-triazole analogue ofσ-quinodimethane, can be generated in situ from 4,5-bis(bromomethyl) derivative (3) by sodium iodide induced 1,4-elimination process. By trapping the 1,4-dimethylene-tr
