Check Digit Verification of cas no

The CAS Registry Mumber 130659-29-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,0,6,5 and 9 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 130659-29:
(8*1)+(7*3)+(6*0)+(5*6)+(4*5)+(3*9)+(2*2)+(1*9)=119
119 % 10 = 9
So 130659-29-9 is a valid CAS Registry Number.

Selective O-methylation of polyhydroxyflavan-3-ols via benzyl carbonates

Van Dyk, Martha S.,Steynberg, Jan P.,Steynberg, Petrus J.,Ferreira, Daneel

, p. 2643 - 2646 (2007/10/02)

The flavan-3-ols (+)-catechin and (-)-epicatechin were selectively transformed to their 3′,4′-di-O-methyl- and 5,7-di-Omethyl-ethers respectively via benzyl carbonates. Such a regioselectivity is facilitated by marked differences in the pKa values of the
