Check Digit Verification of cas no

The CAS Registry Mumber 252917-78-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,2,9,1 and 7 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 252917-78:
(8*2)+(7*5)+(6*2)+(5*9)+(4*1)+(3*7)+(2*7)+(1*8)=155
155 % 10 = 5
So 252917-78-5 is a valid CAS Registry Number.
