Check Digit Verification of cas no
The CAS Registry Mumber 7198-99-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,1,9 and 8 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 7198-99:
(6*7)+(5*1)+(4*9)+(3*8)+(2*9)+(1*9)=134
134 % 10 = 4
So 7198-99-4 is a valid CAS Registry Number.
