Check Digit Verification of cas no

The CAS Registry Mumber 85772-49-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,5,7,7 and 2 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 85772-49:
(7*8)+(6*5)+(5*7)+(4*7)+(3*2)+(2*4)+(1*9)=172
172 % 10 = 2
So 85772-49-2 is a valid CAS Registry Number.
