Check Digit Verification of cas no
The CAS Registry Mumber 22094-93-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,2,0,9 and 4 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 22094-93:
(7*2)+(6*2)+(5*0)+(4*9)+(3*4)+(2*9)+(1*3)=95
95 % 10 = 5
So 22094-93-5 is a valid CAS Registry Number.
