4285-35-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 4285-35-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,2,8 and 5 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 4285-35:
(6*4)+(5*2)+(4*8)+(3*5)+(2*3)+(1*5)=92
92 % 10 = 2
So 4285-35-2 is a valid CAS Registry Number.
