3445-05-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 3445-05-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,4,4 and 5 respectively; the second part has 2 digits, 0 and 5 respectively.Calculate Digit Verification of CAS Registry Number 3445-05:
(6*3)+(5*4)+(4*4)+(3*5)+(2*0)+(1*5)=74
74 % 10 = 4
So 3445-05-4 is a valid CAS Registry Number.
