Check Digit Verification of cas no

The CAS Registry Mumber 1562660-96-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,5,6,2,6,6 and 0 respectively; the second part has 2 digits, 9 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1562660-96:
(9*1)+(8*5)+(7*6)+(6*2)+(5*6)+(4*6)+(3*0)+(2*9)+(1*6)=181
181 % 10 = 1
So 1562660-96-1 is a valid CAS Registry Number.

Protecting group free synthesis of carboxyl-substituted dihydropyrimidines through Biginelli reaction

Ostapchuk, Eugeniy N.,Plaskon, Andrey S.,Grygorenko, Oleksandr O.,Tolmachev, Andrey A.,Ryabukhin, Sergey V.

, p. 1299 - 1303 (2014/01/06)

Chlorotrimethylsilane-promoted Biginelli-type reaction of benzaldehyde, acetoacetic acid derivatives, and various carboxyl-containing ureas was explored. It was found that the steric load of the urea substituents influenced strongly the reaction outcome; in particular, the method was efficient only in the case of unbranched mono-substituted ureas bearing either aliphatic or aromatic groups. The method allows performing a one-pot, protecting group free synthesis of dihydropyrimidines possessing carboxylic functionality.
