Check Digit Verification of cas no

The CAS Registry Mumber 1391405-52-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,9,1,4,0 and 5 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1391405-52:
(9*1)+(8*3)+(7*9)+(6*1)+(5*4)+(4*0)+(3*5)+(2*5)+(1*2)=149
149 % 10 = 9
So 1391405-52-9 is a valid CAS Registry Number.

An efficient and facile synthesis of novel pyrimidine derivatives, N-(4-aryl-6-(pyridin-2-yl)pyrimidin-2-yl)cyanamides, via one-pot multicomponent reaction of different aromatic aldehydes, 2-acetylpyridine, and cyanoguanidine in the presence of NaOH in anhydrous EtOH is reported. Pyrimidine derivatives are extremely important six membered aromatic heterocyclic rings containing two nitrogen atoms which have a wide variety of important biologically activity. This method has the advantages of easy work-up, convenient purification, short reaction times, and high yields.
