Check Digit Verification of cas no

The CAS Registry Mumber 16279-53-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,6,2,7 and 9 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 16279-53:
(7*1)+(6*6)+(5*2)+(4*7)+(3*9)+(2*5)+(1*3)=121
121 % 10 = 1
So 16279-53-1 is a valid CAS Registry Number.
