Check Digit Verification of cas no

The CAS Registry Mumber 1897-49-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,8,9 and 7 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1897-49:
(6*1)+(5*8)+(4*9)+(3*7)+(2*4)+(1*9)=120
120 % 10 = 0
So 1897-49-0 is a valid CAS Registry Number.
