Check Digit Verification of cas no

The CAS Registry Mumber 712278-55-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,1,2,2,7 and 8 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 712278-55:
(8*7)+(7*1)+(6*2)+(5*2)+(4*7)+(3*8)+(2*5)+(1*5)=152
152 % 10 = 2
So 712278-55-2 is a valid CAS Registry Number.
