Check Digit Verification of cas no

The CAS Registry Mumber 1255769-99-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,5,7,6 and 9 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1255769-99:
(9*1)+(8*2)+(7*5)+(6*5)+(5*7)+(4*6)+(3*9)+(2*9)+(1*9)=203
203 % 10 = 3
So 1255769-99-3 is a valid CAS Registry Number.

Biginelli and Hantzsch-type reactions leading to highly functionalized dihydropyrimidinone, thiocoumarin, and pyridopyrimidinone frameworks via ring annulation with β-oxodithioesters

Nandi, Ganesh Chandra,Samai, Subhasis,Singh, Maya Shankar

supporting information; experimental part, p. 7785 - 7795 (2011/02/21)

An efficient and highly convergent route to dihydropyrimidinones (DHPMs) and hitherto unreported dihydropyridopyrimidinones has been developed by one-pot, three-component cyclocondensation of aromatic aldehydes, β-oxodithioesters, and urea/6-amino-1,3-dim
