Check Digit Verification of cas no

The CAS Registry Mumber 87030-12-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,7,0,3 and 0 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 87030-12:
(7*8)+(6*7)+(5*0)+(4*3)+(3*0)+(2*1)+(1*2)=114
114 % 10 = 4
So 87030-12-4 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.

Total Synthesis of (+/-)- and (+)-Latifine
