Check Digit Verification of cas no

The CAS Registry Mumber 93869-84-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,3,8,6 and 9 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 93869-84:
(7*9)+(6*3)+(5*8)+(4*6)+(3*9)+(2*8)+(1*4)=192
192 % 10 = 2
So 93869-84-2 is a valid CAS Registry Number.
