Check Digit Verification of cas no

The CAS Registry Mumber 119925-03-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,9,9,2 and 5 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 119925-03:
(8*1)+(7*1)+(6*9)+(5*9)+(4*2)+(3*5)+(2*0)+(1*3)=140
140 % 10 = 0
So 119925-03-0 is a valid CAS Registry Number.

Highly efficient and chemoselective method for the thioacetalization of aldehydes and transthioacetalization of acetals and acylals catalyzed by H 2SO4-silica under solvent-free conditions

Pourmousavi, Seied Ali,Kazemi, Shaghayegh Sadat

, p. 917 - 923 (2012)

Chemoselective and efficient thioacetalization of a variety of aldehydes was achieved in excellent yields at room temperature using 1,2-ethanedithiol in the presence of catalytic amounts of H2SO4-silica. Thioacetals were also prepare

Sulfonated polyanthracene-catalyzed highly efficient and chemoselective thioacetalization of carbonyl compounds and transthioacetalization of acetals and acylals

Fahid,Pourmousavi

, p. 16 - 29 (2015/10/20)

A straightforward and highly efficient procedure for the thioacetalization of a variety of aldehydes and transthioacetalization of acylals and acetals in good to excellent yields using catalytic amounts of sulfonated polyanthracene (S-PAT) is reported. Th
