The CAS Registry Mumber 74372-23-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,3,7 and 2 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 74372-23:
(7*7)+(6*4)+(5*3)+(4*7)+(3*2)+(2*2)+(1*3)=129
129 % 10 = 9
So 74372-23-9 is a valid CAS Registry Number.
