The CAS Registry Mumber 72331-29-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,2,3,3 and 1 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 72331-29:
(7*7)+(6*2)+(5*3)+(4*3)+(3*1)+(2*2)+(1*9)=104
104 % 10 = 4
So 72331-29-4 is a valid CAS Registry Number.
