Check Digit Verification of cas no

The CAS Registry Mumber 1399975-42-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,9,9,9,7 and 5 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1399975-42:
(9*1)+(8*3)+(7*9)+(6*9)+(5*9)+(4*7)+(3*5)+(2*4)+(1*2)=248
248 % 10 = 8
So 1399975-42-8 is a valid CAS Registry Number.
