Check Digit Verification of cas no

The CAS Registry Mumber 1256037-19-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,6,0,3 and 7 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1256037-19:
(9*1)+(8*2)+(7*5)+(6*6)+(5*0)+(4*3)+(3*7)+(2*1)+(1*9)=140
140 % 10 = 0
So 1256037-19-0 is a valid CAS Registry Number.
