7647-46-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 7647-46-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,6,4 and 7 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 7647-46:
(6*7)+(5*6)+(4*4)+(3*7)+(2*4)+(1*6)=123
123 % 10 = 3
So 7647-46-3 is a valid CAS Registry Number.
