Check Digit Verification of cas no
The CAS Registry Mumber 88191-48-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,8,1,9 and 1 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 88191-48:
(7*8)+(6*8)+(5*1)+(4*9)+(3*1)+(2*4)+(1*8)=164
164 % 10 = 4
So 88191-48-4 is a valid CAS Registry Number.

A new synthetic strategy for catechin-class polyphenols: Concise synthesis of (-)-epicatechin and its 3-O-gallate
Stadlbauer, Sven,Ohmori, Ken,Hattori, Fumihiko,Suzuki, Keisuke

Concise synthesis of (-)-epicatechin and its 3-O-gallate is described, illustrating efficacy of the new strategy for catechin-class polyphenols based on assembly of lithiated fluorobenzene and epoxy alcohol followed by a pyran cyclization. 1,3,5-Trifluorobenzene serves as the A-ring equivalent for functionalization and the pyran annulation.
