Check Digit Verification of cas no

The CAS Registry Mumber 137242-41-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,7,2,4 and 2 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 137242-41:
(8*1)+(7*3)+(6*7)+(5*2)+(4*4)+(3*2)+(2*4)+(1*1)=112
112 % 10 = 2
So 137242-41-2 is a valid CAS Registry Number.
