Check Digit Verification of cas no

The CAS Registry Mumber 195257-72-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,5,2,5 and 7 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 195257-72:
(8*1)+(7*9)+(6*5)+(5*2)+(4*5)+(3*7)+(2*7)+(1*2)=168
168 % 10 = 8
So 195257-72-8 is a valid CAS Registry Number.
