Check Digit Verification of cas no
The CAS Registry Mumber 112664-40-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,2,6,6 and 4 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 112664-40:
(8*1)+(7*1)+(6*2)+(5*6)+(4*6)+(3*4)+(2*4)+(1*0)=101
101 % 10 = 1
So 112664-40-1 is a valid CAS Registry Number.
