Check Digit Verification of cas no

The CAS Registry Mumber 252911-84-5 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 1 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 252911-84:
(8*2)+(7*5)+(6*2)+(5*9)+(4*1)+(3*1)+(2*8)+(1*4)=135
135 % 10 = 5
So 252911-84-5 is a valid CAS Registry Number.
