Check Digit Verification of cas no

The CAS Registry Mumber 61951-98-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,1,9,5 and 1 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 61951-98:
(7*6)+(6*1)+(5*9)+(4*5)+(3*1)+(2*9)+(1*8)=142
142 % 10 = 2
So 61951-98-2 is a valid CAS Registry Number.
