The CAS Registry Mumber 3317-72-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,3,1 and 7 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 3317-72:
(6*3)+(5*3)+(4*1)+(3*7)+(2*7)+(1*2)=74
74 % 10 = 4
So 3317-72-4 is a valid CAS Registry Number.
