697-72-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 697-72-3 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,9 and 7 respectively; the second part has 2 digits, 7 and 2 respectively.Calculate Digit Verification of CAS Registry Number 697-72:
(5*6)+(4*9)+(3*7)+(2*7)+(1*2)=103
103 % 10 = 3
So 697-72-3 is a valid CAS Registry Number.
