Check Digit Verification of cas no

The CAS Registry Mumber 1031756-20-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,3,1,7,5 and 6 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1031756-20:
(9*1)+(8*0)+(7*3)+(6*1)+(5*7)+(4*5)+(3*6)+(2*2)+(1*0)=113
113 % 10 = 3
So 1031756-20-3 is a valid CAS Registry Number.

An improved and green preparation of 3-(alkylthio)propionic acids

Vaismaa, Matti J. P.,Yliniemel?, Sanna M.,Lajunen, Marja K.

, p. 1317 - 1323 (2008/10/09)

An efficient, facile microwave-assisted synthesis has been developed for the preparation of unsymmetrical sulfide derivatives from 3-mercaptopropionic acid and a wide variety of alkyl, allyl or aryl chlorides or bromides. The synthesis performed in ethanol at 80 or 120 °C using sodium hydroxide as a base, selectively without an offensive smell, generates 3-(alkylthio)propionic acids in good yields. Effects of reaction components, temperature, and the heating technique on the formation of the product and side-products were studied.
