123966-64-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 123966-64-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,3,9,6 and 6 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 123966-64:
(8*1)+(7*2)+(6*3)+(5*9)+(4*6)+(3*6)+(2*6)+(1*4)=143
143 % 10 = 3
So 123966-64-3 is a valid CAS Registry Number.
