Check Digit Verification of cas no
The CAS Registry Mumber 209049-18-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,9,0,4 and 9 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 209049-18:
(8*2)+(7*0)+(6*9)+(5*0)+(4*4)+(3*9)+(2*1)+(1*8)=123
123 % 10 = 3
So 209049-18-3 is a valid CAS Registry Number.
