Check Digit Verification of cas no

The CAS Registry Mumber 137041-52-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,7,0,4 and 1 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 137041-52:
(8*1)+(7*3)+(6*7)+(5*0)+(4*4)+(3*1)+(2*5)+(1*2)=102
102 % 10 = 2
So 137041-52-2 is a valid CAS Registry Number.
