The CAS Registry Mumber 4973-37-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,9,7 and 3 respectively; the second part has 2 digits, 3 and 7 respectively. Calculate Digit Verification of CAS Registry Number 4973-37: (6*4)+(5*9)+(4*7)+(3*3)+(2*3)+(1*7)=119 119 % 10 = 9 So 4973-37-9 is a valid CAS Registry Number.
