Check Digit Verification of cas no

The CAS Registry Mumber 1263144-93-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,3,1,4 and 4 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1263144-93:
(9*1)+(8*2)+(7*6)+(6*3)+(5*1)+(4*4)+(3*4)+(2*9)+(1*3)=139
139 % 10 = 9
So 1263144-93-9 is a valid CAS Registry Number.
