231307-22-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 231307-22-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,3,1,3,0 and 7 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 231307-22:
(8*2)+(7*3)+(6*1)+(5*3)+(4*0)+(3*7)+(2*2)+(1*2)=85
85 % 10 = 5
So 231307-22-5 is a valid CAS Registry Number.
