The CAS Registry Mumber 2455-37-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,4,5 and 5 respectively; the second part has 2 digits, 3 and 7 respectively. Calculate Digit Verification of CAS Registry Number 2455-37: (6*2)+(5*4)+(4*5)+(3*5)+(2*3)+(1*7)=80 80 % 10 = 0 So 2455-37-0 is a valid CAS Registry Number.
