Check Digit Verification of cas no
The CAS Registry Mumber 56423-63-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,6,4,2 and 3 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 56423-63:
(7*5)+(6*6)+(5*4)+(4*2)+(3*3)+(2*6)+(1*3)=123
123 % 10 = 3
So 56423-63-3 is a valid CAS Registry Number.
