5Check Digit Verification of cas no
The CAS Registry Mumber 1328-50-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,3,2 and 8 respectively; the second part has 2 digits, 5 and 0 respectively.Calculate Digit Verification of CAS Registry Number 1328-50:
(6*1)+(5*3)+(4*2)+(3*8)+(2*5)+(1*0)=63
63 % 10 = 3
So 1328-50-3 is a valid CAS Registry Number.
