Check Digit Verification of cas no

The CAS Registry Mumber 127799-20-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,7,7,9 and 9 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 127799-20:
(8*1)+(7*2)+(6*7)+(5*7)+(4*9)+(3*9)+(2*2)+(1*0)=166
166 % 10 = 6
So 127799-20-6 is a valid CAS Registry Number.
