Check Digit Verification of cas no

The CAS Registry Mumber 72990-84-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,2,9,9 and 0 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 72990-84:
(7*7)+(6*2)+(5*9)+(4*9)+(3*0)+(2*8)+(1*4)=162
162 % 10 = 2
So 72990-84-2 is a valid CAS Registry Number.
