Check Digit Verification of cas no

The CAS Registry Mumber 1309044-47-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,0,9,0,4 and 4 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1309044-47:
(9*1)+(8*3)+(7*0)+(6*9)+(5*0)+(4*4)+(3*4)+(2*4)+(1*7)=130
130 % 10 = 0
So 1309044-47-0 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.
