Check Digit Verification of cas no

The CAS Registry Mumber 136779-28-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,6,7,7 and 9 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 136779-28:
(8*1)+(7*3)+(6*6)+(5*7)+(4*7)+(3*9)+(2*2)+(1*8)=167
167 % 10 = 7
So 136779-28-7 is a valid CAS Registry Number.
