1Check Digit Verification of cas no
The CAS Registry Mumber 574-65-2 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,7 and 4 respectively; the second part has 2 digits, 6 and 5 respectively.Calculate Digit Verification of CAS Registry Number 574-65:
(5*5)+(4*7)+(3*4)+(2*6)+(1*5)=82
82 % 10 = 2
So 574-65-2 is a valid CAS Registry Number.
