Check Digit Verification of cas no

The CAS Registry Mumber 90363-12-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,3,6 and 3 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 90363-12:
(7*9)+(6*0)+(5*3)+(4*6)+(3*3)+(2*1)+(1*2)=115
115 % 10 = 5
So 90363-12-5 is a valid CAS Registry Number.

A Novel Synthesis of Catechin-type Compounds: Synthesis of 6-Acetyl-7-hydroxy-2,3-trans-flavan-3-ol

Jain, A. C.,Arya, Prabhat,Nayyar, Naresh K.

, p. 1116 - 1118 (2007/10/02)

The new method involves epoxidation of C-cinnamylated polyphenols, followed by hetero-cyclisation in the presence of H2SO4 - CH3COOH medium and final deacetylation.Thus, 5-C-cinnamylresacetophenone (II) has been converted into 6-acetyl-7-hydroxy-2,3-trans-flavan-3-ol (V) through epoxide (III) and the 3-O-acetyl derivative (IV).
