7250-04-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 7250-04-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,2,5 and 0 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 7250-04:
(6*7)+(5*2)+(4*5)+(3*0)+(2*0)+(1*4)=76
76 % 10 = 6
So 7250-04-6 is a valid CAS Registry Number.
