62564-58-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 62564-58-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,2,5,6 and 4 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 62564-58:
(7*6)+(6*2)+(5*5)+(4*6)+(3*4)+(2*5)+(1*8)=133
133 % 10 = 3
So 62564-58-3 is a valid CAS Registry Number.
