Check Digit Verification of cas no

The CAS Registry Mumber 1309871-85-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,0,9,8,7 and 1 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1309871-85:
(9*1)+(8*3)+(7*0)+(6*9)+(5*8)+(4*7)+(3*1)+(2*8)+(1*5)=179
179 % 10 = 9
So 1309871-85-9 is a valid CAS Registry Number.

First regiocontrolled synthesis of procyanidin B6, a catechin dimer with rare connectivity: A halo-capping strategy for formation of 4,6-interflavan bonds

Watanabe, Gen,Ohmori, Ken,Suzuki, Keisuke

supporting information, p. 5210 - 5212 (2013/06/27)

The first regiocontrolled synthesis of procyanidin B6, a dimer with a rare 4,6-interflavan linkage, is described. Regioselective linking was achieved by the halo-capping strategy followed by removal of all the benzyl protecting groups and the halo-caps by one-pot hydrogenolysis.

Integrated synthetic strategy for higher catechin oligomers

Ohmori, Ken,Shono, Tomohiro,Hatakoshi, Yuki,Yano, Takahisa,Suzuki, Keisuke

supporting information; experimental part, p. 4862 - 4867 (2011/06/26)

Chain linked: An integrated strategy for the rapid assembly of catechin oligomers has been developed, thus enabling access to higher oligomers ranging from 6- to 24-mers. The method exploits an orthogonal, block-type coupling strategy (see scheme). Copyright
