Check Digit Verification of cas no
The CAS Registry Mumber 132113-74-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,2,1,1 and 3 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 132113-74:
(8*1)+(7*3)+(6*2)+(5*1)+(4*1)+(3*3)+(2*7)+(1*4)=77
77 % 10 = 7
So 132113-74-7 is a valid CAS Registry Number.

The preparation of the aza-spirobicyclic system of discorhabdin C via an intramolecular phenolate alkylation
Kublak,Confalone
, p. 3845 - 3848 (2007/10/02)
A model study designed for the synthesis of the discorhabdin alkaloids is presented. The key reaction is the intramolecular para-phenolate alkylation of the mesyloxy aminonaphthoquinone 10 to afford the target tetracyclic system 11.
