Check Digit Verification of cas no

The CAS Registry Mumber 191275-06-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,1,2,7 and 5 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 191275-06:
(8*1)+(7*9)+(6*1)+(5*2)+(4*7)+(3*5)+(2*0)+(1*6)=136
136 % 10 = 6
So 191275-06-6 is a valid CAS Registry Number.
