Check Digit Verification of cas no
The CAS Registry Mumber 8003-22-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 8,0,0 and 3 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 8003-22:
(6*8)+(5*0)+(4*0)+(3*3)+(2*2)+(1*2)=63
63 % 10 = 3
So 8003-22-3 is a valid CAS Registry Number.
