The CAS Registry Mumber 1834-55-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,8,3 and 4 respectively; the second part has 2 digits, 5 and 5 respectively. Calculate Digit Verification of CAS Registry Number 1834-55: (6*1)+(5*8)+(4*3)+(3*4)+(2*5)+(1*5)=85 85 % 10 = 5 So 1834-55-5 is a valid CAS Registry Number.
