Check Digit Verification of cas no
The CAS Registry Mumber 22905-22-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,2,9,0 and 5 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 22905-22:
(7*2)+(6*2)+(5*9)+(4*0)+(3*5)+(2*2)+(1*2)=92
92 % 10 = 2
So 22905-22-2 is a valid CAS Registry Number.
