Check Digit Verification of cas no
The CAS Registry Mumber 223429-05-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,3,4,2 and 9 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 223429-05:
(8*2)+(7*2)+(6*3)+(5*4)+(4*2)+(3*9)+(2*0)+(1*5)=108
108 % 10 = 8
So 223429-05-8 is a valid CAS Registry Number.
