Check Digit Verification of cas no

The CAS Registry Mumber 1612159-31-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,1,2,1,5 and 9 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1612159-31:
(9*1)+(8*6)+(7*1)+(6*2)+(5*1)+(4*5)+(3*9)+(2*3)+(1*1)=135
135 % 10 = 5
So 1612159-31-5 is a valid CAS Registry Number.

Synthesis of 3-(3-methyl-1-aryl-1H-pyrazol-5-yl)-2H-2-chromen-2-one derivatives via a one-pot, three-component reaction

Alizadeh, Abdolali,Ghanbaripour, Rashid

, p. 1635 - 1640 (2014)

An efficient synthesis of 3-(3-methyl-1-aryl-1H-pyrazol-5-yl)-2H-2-chromen- 2-one derivatives by the reaction of salicylaldehydes, 4-hydroxy-6-methyl-2H- pyran-2-one, and arylhydrazine in acetonitrile under reflux condition and in the presence of piperidine is reported. This three-component reaction has some advantages such as ease of handling, good yields, and easy purification. All structures were confirmed by infrared, mass, 1H NMR, and 13C NMR spectroscopy.
