Check Digit Verification of cas no
The CAS Registry Mumber 3223-90-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,2,2 and 3 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 3223-90:
(6*3)+(5*2)+(4*2)+(3*3)+(2*9)+(1*0)=63
63 % 10 = 3
So 3223-90-3 is a valid CAS Registry Number.
