Check Digit Verification of cas no

The CAS Registry Mumber 1261161-43-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,1,1,6 and 1 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1261161-43:
(9*1)+(8*2)+(7*6)+(6*1)+(5*1)+(4*6)+(3*1)+(2*4)+(1*3)=116

supporting information; experimental part, p. 296 - 299 (2011/03/22)

N-Vinyl ureas are emerging as a valuable class of compounds with both nucleophilic and electrophilic reactivity. They may be made by capturing the enamine tautomer of an imine with an isocyanate, a reaction which in general leads to the E isomer of the vi
