Check Digit Verification of cas no

The CAS Registry Mumber 37542-84-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,7,5,4 and 2 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 37542-84:
(7*3)+(6*7)+(5*5)+(4*4)+(3*2)+(2*8)+(1*4)=130
130 % 10 = 0
So 37542-84-0 is a valid CAS Registry Number.
