Check Digit Verification of cas no

The CAS Registry Mumber 1173658-63-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,7,3,6,5 and 8 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1173658-63:
(9*1)+(8*1)+(7*7)+(6*3)+(5*6)+(4*5)+(3*8)+(2*6)+(1*3)=173
173 % 10 = 3
So 1173658-63-3 is a valid CAS Registry Number.

Convenient one-pot synthesis of 3,4-dihydropyrimidin-2(1H)-ones using TMSCl as a catalyst with ultrasonic irradiation in DMF

Guo, Sheng-Rong,Yuan, Yan-Qin

experimental part, p. 2205 - 2220 (2009/11/30)

3,4-Dihydropyrimidin-2(1H)-one and their derivatives were synthesized in good yields (90-99%) by a one-pot, three-component Biginelli cyclocondensation of dimedone, aldehydes, and urea in the presence of trimethylsilyl chloride (TMSCl) in dimethylformamid
