63822-45-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 63822-45-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,3,8,2 and 2 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 63822-45:
(7*6)+(6*3)+(5*8)+(4*2)+(3*2)+(2*4)+(1*5)=127
127 % 10 = 7
So 63822-45-7 is a valid CAS Registry Number.
