Check Digit Verification of cas no

The CAS Registry Mumber 220472-55-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,0,4,7 and 2 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 220472-55:
(8*2)+(7*2)+(6*0)+(5*4)+(4*7)+(3*2)+(2*5)+(1*5)=99
99 % 10 = 9
So 220472-55-9 is a valid CAS Registry Number.

The synthesis of conformationally constrained analogues of the ACE inhibitor Idrapril

Jones, Iwan G.,Jones, Wyn,North, Michael

, p. 279 - 290 (1999)

A conformationally constrained analogue 3 of the ACE inhibitor Idrapril has been prepared by a five-step synthesis. The key step in the synthesis is the desymmetrization of endo-norborn-5-ene-2,3-dicarboxylic anhydride 4 by reaction with t-butyl (S)-prolinate.
