The CAS Registry Mumber 219913-18-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,9,9,1 and 3 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 219913-18:
(8*2)+(7*1)+(6*9)+(5*9)+(4*1)+(3*3)+(2*1)+(1*8)=145
145 % 10 = 5
So 219913-18-5 is a valid CAS Registry Number.
