The CAS Registry Mumber 196803-48-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,6,8,0 and 3 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 196803-48:
(8*1)+(7*9)+(6*6)+(5*8)+(4*0)+(3*3)+(2*4)+(1*8)=172
172 % 10 = 2
So 196803-48-2 is a valid CAS Registry Number.
