Check Digit Verification of cas no
The CAS Registry Mumber 2198-77-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,1,9 and 8 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 2198-77:
(6*2)+(5*1)+(4*9)+(3*8)+(2*7)+(1*7)=98
98 % 10 = 8
So 2198-77-8 is a valid CAS Registry Number.
