22680-65-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 22680-65-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,2,6,8 and 0 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 22680-65:
(7*2)+(6*2)+(5*6)+(4*8)+(3*0)+(2*6)+(1*5)=105
105 % 10 = 5
So 22680-65-5 is a valid CAS Registry Number.
