81633-51-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 81633-51-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,6,3 and 3 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 81633-51:
(7*8)+(6*1)+(5*6)+(4*3)+(3*3)+(2*5)+(1*1)=124
124 % 10 = 4
So 81633-51-4 is a valid CAS Registry Number.

Sakai, Shin-ichiro,Saito, Naoki,Hirose, Naohiro,Yamanaka, Etsuji
, p. 99 - 103 (2007/10/02)
Reserpiline 4 and isoreserpiline 3 were first synthesized through 5,6-dimethoxyindole derivative 11, 12 and amine synthon 8 which was already derived from natural oxindole alkaloids 9, 10 and/or by the total syntheses.
