22773-07-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 22773-07-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,2,7,7 and 3 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 22773-07:
(7*2)+(6*2)+(5*7)+(4*7)+(3*3)+(2*0)+(1*7)=105
105 % 10 = 5
So 22773-07-5 is a valid CAS Registry Number.
