Check Digit Verification of cas no

The CAS Registry Mumber 89726-19-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,7,2 and 6 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 89726-19:
(7*8)+(6*9)+(5*7)+(4*2)+(3*6)+(2*1)+(1*9)=182
182 % 10 = 2
So 89726-19-2 is a valid CAS Registry Number.
