Check Digit Verification of cas no

The CAS Registry Mumber 669772-25-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,6,9,7,7 and 2 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 669772-25:
(8*6)+(7*6)+(6*9)+(5*7)+(4*7)+(3*2)+(2*2)+(1*5)=222
222 % 10 = 2
So 669772-25-2 is a valid CAS Registry Number.
