Check Digit Verification of cas no

The CAS Registry Mumber 197391-49-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,7,3,9 and 1 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 197391-49:
(8*1)+(7*9)+(6*7)+(5*3)+(4*9)+(3*1)+(2*4)+(1*9)=184
184 % 10 = 4
So 197391-49-4 is a valid CAS Registry Number.
