457638-62-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 457638-62-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,5,7,6,3 and 8 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 457638-62:
(8*4)+(7*5)+(6*7)+(5*6)+(4*3)+(3*8)+(2*6)+(1*2)=189
189 % 10 = 9
So 457638-62-9 is a valid CAS Registry Number.
