Check Digit Verification of cas no
The CAS Registry Mumber 22243-90-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,2,2,4 and 3 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 22243-90:
(7*2)+(6*2)+(5*2)+(4*4)+(3*3)+(2*9)+(1*0)=79
79 % 10 = 9
So 22243-90-9 is a valid CAS Registry Number.
