Check Digit Verification of cas no

The CAS Registry Mumber 199680-24-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,9,6,8 and 0 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 199680-24:
(8*1)+(7*9)+(6*9)+(5*6)+(4*8)+(3*0)+(2*2)+(1*4)=195
195 % 10 = 5
So 199680-24-5 is a valid CAS Registry Number.
