Check Digit Verification of cas no

The CAS Registry Mumber 120703-15-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,0,7,0 and 3 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 120703-15:
(8*1)+(7*2)+(6*0)+(5*7)+(4*0)+(3*3)+(2*1)+(1*5)=73
73 % 10 = 3
So 120703-15-3 is a valid CAS Registry Number.

Transesterification of various methyl esters under mild conditions catalyzed by tetranuclear zinc cluster

Iwasaki, Takanori,Maegawa, Yusuke,Hayashi, Yukiko,Ohshima, Takashi,Mashima, Kazushi

, p. 5147 - 5150 (2008)

(Chemical Equation Presented) A new catalytic transesterification promoted by a tetranuclear zinc cluster was developed. The mild reaction conditions enabled the reactions of various functionalized substrates to proceed in good to high yield. A large-scale reaction under solvent-free conditions proceeded with a low E-factor value (0.66), indicating the high environmental and economical advantage of the present catalysis.
