Check Digit Verification of cas no

The CAS Registry Mumber 19900-72-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,9,0 and 0 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 19900-72:
(7*1)+(6*9)+(5*9)+(4*0)+(3*0)+(2*7)+(1*2)=122
122 % 10 = 2
So 19900-72-2 is a valid CAS Registry Number.
