91877-33-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 91877-33-7 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 3 respectively.
Calculate Digit Verification of CAS Registry Number 91877-33:
(7*9)+(6*1)+(5*8)+(4*7)+(3*7)+(2*3)+(1*3)=167
167 % 10 = 7
So 91877-33-7 is a valid CAS Registry Number.

PRELIMINARY RESULTS IN CYCLOADDITION OF DIPHENYLNITRILIMINE TO PHOSPHINDOLE OXIDES
Sedqui, Ahmed,Vebrel, Joel,Laude, Bernard
, p. 965 - 968 (2007/10/02)
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.
