Check Digit Verification of cas no

The CAS Registry Mumber 7192-79-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,1,9 and 2 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 7192-79:
(6*7)+(5*1)+(4*9)+(3*2)+(2*7)+(1*9)=112
112 % 10 = 2
So 7192-79-2 is a valid CAS Registry Number.
