Check Digit Verification of cas no

The CAS Registry Mumber 1262995-46-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,2,9,9 and 5 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1262995-46:
(9*1)+(8*2)+(7*6)+(6*2)+(5*9)+(4*9)+(3*5)+(2*4)+(1*6)=189
189 % 10 = 9
So 1262995-46-9 is a valid CAS Registry Number.

Oxidative desulfurization of disubstituted thioureas using Pb(II) salts and investigation of pKa-dependent regioselective N-acylation

Ghosh, Harisadhan,Sarkar, Soumya,Ali, Abdur Rezzak,Patel, Bhisma K.

experimental part, p. 1 - 11 (2010/10/01)

A highly efficient method for the N-acylation of both symmetrical and unsymmetrical thioureas by the use of lead (II) salts and triethylamine has been achieved. The reaction gives regioselective N-acylated product for unsymmetrical thiourea. For unsymmetrical thiuourea, regioselective N-acylation takes place towards the amine having lower pKa.A linear correlation between the pKas of the amines and the regioselective Nacylation is found. Another attractive feature of this transformation is that lead sulfide, which is important to material science, is obtained as a side product (nanocubes of 20 nm).
