Check Digit Verification of cas no

The CAS Registry Mumber 1372144-55-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,7,2,1,4 and 4 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1372144-55:
(9*1)+(8*3)+(7*7)+(6*2)+(5*1)+(4*4)+(3*4)+(2*5)+(1*5)=142
142 % 10 = 2
So 1372144-55-2 is a valid CAS Registry Number.
