457644-69-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 457644-69-8 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, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 457644-69:
(8*4)+(7*5)+(6*7)+(5*6)+(4*4)+(3*4)+(2*6)+(1*9)=188
188 % 10 = 8
So 457644-69-8 is a valid CAS Registry Number.
