745-64-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 745-64-2 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 7,4 and 5 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 745-64:
(5*7)+(4*4)+(3*5)+(2*6)+(1*4)=82
82 % 10 = 2
So 745-64-2 is a valid CAS Registry Number.
