Check Digit Verification of cas no

The CAS Registry Mumber 37521-01-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,7,5,2 and 1 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 37521-01:
(7*3)+(6*7)+(5*5)+(4*2)+(3*1)+(2*0)+(1*1)=100
100 % 10 = 0
So 37521-01-0 is a valid CAS Registry Number.
