223704-08-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 223704-08-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,3,7,0 and 4 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 223704-08:
(8*2)+(7*2)+(6*3)+(5*7)+(4*0)+(3*4)+(2*0)+(1*8)=103
103 % 10 = 3
So 223704-08-3 is a valid CAS Registry Number.
