7090-21-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 7090-21-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,0,9 and 0 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 7090-21:
(6*7)+(5*0)+(4*9)+(3*0)+(2*2)+(1*1)=83
83 % 10 = 3
So 7090-21-3 is a valid CAS Registry Number.
