Check Digit Verification of cas no

The CAS Registry Mumber 91877-31-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,8,7 and 7 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 91877-31:
(7*9)+(6*1)+(5*8)+(4*7)+(3*7)+(2*3)+(1*1)=165
165 % 10 = 5
So 91877-31-5 is a valid CAS Registry Number.

PRELIMINARY RESULTS IN CYCLOADDITION OF DIPHENYLNITRILIMINE TO PHOSPHINDOLE OXIDES

Sedqui, Ahmed,Vebrel, Joel,Laude, Bernard

, p. 965 - 968 (1984)

Diphenylnitrilimine cycloaddition reactions to two phosphindoles oxides are regiospecific ans stereospecific.The approach of the dipole occurs from the less hindered diastereotopic side of the dipolarophile.
