Check Digit Verification of cas no
The CAS Registry Mumber 22319-49-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,2,3,1 and 9 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 22319-49:
(7*2)+(6*2)+(5*3)+(4*1)+(3*9)+(2*4)+(1*9)=89
89 % 10 = 9
So 22319-49-9 is a valid CAS Registry Number.
