143264-79-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 143264-79-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,3,2,6 and 4 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 143264-79:
(8*1)+(7*4)+(6*3)+(5*2)+(4*6)+(3*4)+(2*7)+(1*9)=123
123 % 10 = 3
So 143264-79-3 is a valid CAS Registry Number.
