The CAS Registry Mumber 3855-49-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,8,5 and 5 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 3855-49:
(6*3)+(5*8)+(4*5)+(3*5)+(2*4)+(1*9)=110
110 % 10 = 0
So 3855-49-0 is a valid CAS Registry Number.
