2245-02-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 2245-02-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,2,4 and 5 respectively; the second part has 2 digits, 0 and 2 respectively.Calculate Digit Verification of CAS Registry Number 2245-02:
(6*2)+(5*2)+(4*4)+(3*5)+(2*0)+(1*2)=55
55 % 10 = 5
So 2245-02-5 is a valid CAS Registry Number.
