Check Digit Verification of cas no

The CAS Registry Mumber 1235751-22-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,3,5,7,5 and 1 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1235751-22:
(9*1)+(8*2)+(7*3)+(6*5)+(5*7)+(4*5)+(3*1)+(2*2)+(1*2)=140
140 % 10 = 0
So 1235751-22-0 is a valid CAS Registry Number.
