The CAS Registry Mumber 121838-18-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,1,8,3 and 8 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 121838-18:
(8*1)+(7*2)+(6*1)+(5*8)+(4*3)+(3*8)+(2*1)+(1*8)=114
114 % 10 = 4
So 121838-18-4 is a valid CAS Registry Number.
