Check Digit Verification of cas no

The CAS Registry Mumber 4897-74-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,8,9 and 7 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 4897-74:
(6*4)+(5*8)+(4*9)+(3*7)+(2*7)+(1*4)=139
139 % 10 = 9
So 4897-74-9 is a valid CAS Registry Number.
