Check Digit Verification of cas no
The CAS Registry Mumber 207118-10-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,7,1,1 and 8 respectively; the second part has 2 digits, 1 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 207118-10:
(8*2)+(7*0)+(6*7)+(5*1)+(4*1)+(3*8)+(2*1)+(1*0)=93
93 % 10 = 3
So 207118-10-3 is a valid CAS Registry Number.
