Check Digit Verification of cas no

The CAS Registry Mumber 923235-54-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,2,3,2,3 and 5 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 923235-54:
(8*9)+(7*2)+(6*3)+(5*2)+(4*3)+(3*5)+(2*5)+(1*4)=155
155 % 10 = 5
So 923235-54-5 is a valid CAS Registry Number.

A convenient one-pot Biginelli reaction catalyzed by Y(OAc)3: An improved protocol for the synthesis of 3,4-dihydropyrimidin-2(1H)-ones and their sulfur analogues

Aridoss, Gopalakrishnan,Jeong, Yeon Tae

experimental part, p. 863 - 868 (2010/10/19)

Yttrium(III) acetate hydrate-catalyzed novel synthesis of 3,4-dihydropyrimidin-2(1H)-(thio)one derivatives was achieved through one-pot three-component condensation of diversified aldehydes, β-ketoesters and urea or N-methylurea or thiourea with a molar r
