Check Digit Verification of cas no

The CAS Registry Mumber 1261582-29-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,1,5,8 and 2 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1261582-29:
(9*1)+(8*2)+(7*6)+(6*1)+(5*5)+(4*8)+(3*2)+(2*2)+(1*9)=149
149 % 10 = 9
So 1261582-29-9 is a valid CAS Registry Number.

Exploiting enzymatic regioselectivity: A facile methodology for the synthesis of polyhydroxylated hybrid compounds

Magrone, Pietro,Cavallo, Francesco,Panzeri, Walter,Passarella, Daniele,Riva, Sergio

experimental part, p. 5583 - 5590 (2011/02/18)

Polyhydroxylated hybrid molecules have been synthesized using a protocol based on the regioselective acylation of the target compounds with activated dicarboxylic acids catalyzed by Novozym-435. The procedure implies that the mixed ester derivatives prepared and isolated from the first esterification step act as acylating agents in the second esterification step.
