Check Digit Verification of cas no

The CAS Registry Mumber 883196-19-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,8,3,1,9 and 6 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 883196-19:
(8*8)+(7*8)+(6*3)+(5*1)+(4*9)+(3*6)+(2*1)+(1*9)=208
208 % 10 = 8
So 883196-19-8 is a valid CAS Registry Number.

General synthesis of epi-series catechins and their 3-gallates: Reverse polarity strategy

Ohmori, Ken,Yano, Takahisa,Suzuki, Keisuke

supporting information; experimental part, p. 2693 - 2696 (2010/08/21)

A general synthetic route to the epi-series catechins was developed based on the reverse polarity strategy. Aromatic nucleophilic substitution reaction followed by the sulfinyl-metal exchange and cyclization enabled stereo-controlled access to various members of epi-series catechins and their 3-gallates.
