Check Digit Verification of cas no

The CAS Registry Mumber 252905-91-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,2,9,0 and 5 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 252905-91:
(8*2)+(7*5)+(6*2)+(5*9)+(4*0)+(3*5)+(2*9)+(1*1)=142
142 % 10 = 2
So 252905-91-2 is a valid CAS Registry Number.
