Check Digit Verification of cas no
The CAS Registry Mumber 116912-64-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,6,9,1 and 2 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 116912-64:
(8*1)+(7*1)+(6*6)+(5*9)+(4*1)+(3*2)+(2*6)+(1*4)=122
122 % 10 = 2
So 116912-64-2 is a valid CAS Registry Number.
