Check Digit Verification of cas no
The CAS Registry Mumber 2198-75-6 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 5 respectively.
Calculate Digit Verification of CAS Registry Number 2198-75:
(6*2)+(5*1)+(4*9)+(3*8)+(2*7)+(1*5)=96
96 % 10 = 6
So 2198-75-6 is a valid CAS Registry Number.
