Check Digit Verification of cas no

The CAS Registry Mumber 1256270-66-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,6,2,7 and 0 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1256270-66:
(9*1)+(8*2)+(7*5)+(6*6)+(5*2)+(4*7)+(3*0)+(2*6)+(1*6)=152
152 % 10 = 2
So 1256270-66-2 is a valid CAS Registry Number.
