4435-60-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 4435-60-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,4,3 and 5 respectively; the second part has 2 digits, 6 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 4435-60:
(6*4)+(5*4)+(4*3)+(3*5)+(2*6)+(1*0)=83
83 % 10 = 3
So 4435-60-3 is a valid CAS Registry Number.
