Check Digit Verification of cas no

The CAS Registry Mumber 73770-87-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,3,7,7 and 0 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 73770-87:
(7*7)+(6*3)+(5*7)+(4*7)+(3*0)+(2*8)+(1*7)=153
153 % 10 = 3
So 73770-87-3 is a valid CAS Registry Number.
