Check Digit Verification of cas no

The CAS Registry Mumber 91902-80-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,9,0 and 2 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 91902-80:
(7*9)+(6*1)+(5*9)+(4*0)+(3*2)+(2*8)+(1*0)=136
136 % 10 = 6
So 91902-80-6 is a valid CAS Registry Number.
