Check Digit Verification of cas no

The CAS Registry Mumber 78899-37-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,8,8,9 and 9 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 78899-37:
(7*7)+(6*8)+(5*8)+(4*9)+(3*9)+(2*3)+(1*7)=213
213 % 10 = 3
So 78899-37-3 is a valid CAS Registry Number.
