223908-31-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 223908-31-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,3,9,0 and 8 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 223908-31:
(8*2)+(7*2)+(6*3)+(5*9)+(4*0)+(3*8)+(2*3)+(1*1)=124
124 % 10 = 4
So 223908-31-4 is a valid CAS Registry Number.
