2284-35-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 2284-35-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,2,8 and 4 respectively; the second part has 2 digits, 3 and 5 respectively.Calculate Digit Verification of CAS Registry Number 2284-35:
(6*2)+(5*2)+(4*8)+(3*4)+(2*3)+(1*5)=77
77 % 10 = 7
So 2284-35-7 is a valid CAS Registry Number.
