221909-96-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 221909-96-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,1,9,0 and 9 respectively; the second part has 2 digits, 9 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 221909-96:
(8*2)+(7*2)+(6*1)+(5*9)+(4*0)+(3*9)+(2*9)+(1*6)=132
132 % 10 = 2
So 221909-96-2 is a valid CAS Registry Number.
