64465-33-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 64465-33-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,4,4,6 and 5 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 64465-33:
(7*6)+(6*4)+(5*4)+(4*6)+(3*5)+(2*3)+(1*3)=134
134 % 10 = 4
So 64465-33-4 is a valid CAS Registry Number.
