Check Digit Verification of cas no

The CAS Registry Mumber 221377-20-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,1,3,7 and 7 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 221377-20:
(8*2)+(7*2)+(6*1)+(5*3)+(4*7)+(3*7)+(2*2)+(1*0)=104
104 % 10 = 4
So 221377-20-4 is a valid CAS Registry Number.

Guilet, David,Morel, Cécile,Noyer, Nathalie,Cornec, Maryse,Séraphin, Denis,Wiart, Christian,Hadi, A. Hamid A.,Sévenet, Thierry,Richomme, Pascal,Bruneton, Jean

, p. 67 - 76 (2007/10/03)

Four new 4-phenylcoumarins, disparinols A and B, isodisparinols A and B, having a 2-hydroxy-3-methylbut-3-enyl substituent were isolated from the bark of Calophyllum dispar (Clusiaceae). Their structures were established by means of spectroscopic studies and confirmed by hemisynthesis.
