423761-66-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 423761-66-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,2,3,7,6 and 1 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 423761-66:
(8*4)+(7*2)+(6*3)+(5*7)+(4*6)+(3*1)+(2*6)+(1*6)=144
144 % 10 = 4
So 423761-66-4 is a valid CAS Registry Number.
