Check Digit Verification of cas no

The CAS Registry Mumber 133957-06-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,3,9,5 and 7 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 133957-06:
(8*1)+(7*3)+(6*3)+(5*9)+(4*5)+(3*7)+(2*0)+(1*6)=139
139 % 10 = 9
So 133957-06-9 is a valid CAS Registry Number.
