Check Digit Verification of cas no

The CAS Registry Mumber 1207174-49-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,0,7,1,7 and 4 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1207174-49:
(9*1)+(8*2)+(7*0)+(6*7)+(5*1)+(4*7)+(3*4)+(2*4)+(1*9)=129
129 % 10 = 9
So 1207174-49-9 is a valid CAS Registry Number.

experimental part, p. 135 - 143 (2010/03/24)

A green approach to the synthesis of polyfunctionalized pyrazolo[4',3':5,6]pyrido[2,3-d]pyrimidines was successfully realized via multicomponent reactions of aldehydes, 3-methyl-1-phenyl-1H-pyrazol-5-amine, and 1-methylbarbituric acid in water under microwave irradiation without catalyst. This protocol has the prominent advantages of environmental friendliness, short reaction time, excellent yields, low cost, easy operation, and broad scope of applicability.
