457644-71-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 457644-71-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,5,7,6,4 and 4 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 457644-71:
(8*4)+(7*5)+(6*7)+(5*6)+(4*4)+(3*4)+(2*7)+(1*1)=182
182 % 10 = 2
So 457644-71-2 is a valid CAS Registry Number.
