223123-65-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 223123-65-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,3,1,2 and 3 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 223123-65:
(8*2)+(7*2)+(6*3)+(5*1)+(4*2)+(3*3)+(2*6)+(1*5)=87
87 % 10 = 7
So 223123-65-7 is a valid CAS Registry Number.
