Check Digit Verification of cas no

The CAS Registry Mumber 1256161-30-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,6,1,6 and 1 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1256161-30:
(9*1)+(8*2)+(7*5)+(6*6)+(5*1)+(4*6)+(3*1)+(2*3)+(1*0)=134
134 % 10 = 4
So 1256161-30-4 is a valid CAS Registry Number.
