7641-46-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 7641-46-5 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 1 respectively; the second part has 2 digits, 4 and 6 respectively.Calculate Digit Verification of CAS Registry Number 7641-46:
(6*7)+(5*6)+(4*4)+(3*1)+(2*4)+(1*6)=105
105 % 10 = 5
So 7641-46-5 is a valid CAS Registry Number.
