Check Digit Verification of cas no

The CAS Registry Mumber 1256350-26-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,6,3,5 and 0 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1256350-26:
(9*1)+(8*2)+(7*5)+(6*6)+(5*3)+(4*5)+(3*0)+(2*2)+(1*6)=141
141 % 10 = 1
So 1256350-26-1 is a valid CAS Registry Number.
