656-03-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 656-03-1 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,5 and 6 respectively; the second part has 2 digits, 0 and 3 respectively.Calculate Digit Verification of CAS Registry Number 656-03:
(5*6)+(4*5)+(3*6)+(2*0)+(1*3)=71
71 % 10 = 1
So 656-03-1 is a valid CAS Registry Number.
