The CAS Registry Mumber 4697-59-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,6,9 and 7 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 4697-59:
(6*4)+(5*6)+(4*9)+(3*7)+(2*5)+(1*9)=130
130 % 10 = 0
So 4697-59-0 is a valid CAS Registry Number.
