Check Digit Verification of cas no
The CAS Registry Mumber 1604-43-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,6,0 and 4 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1604-43:
(6*1)+(5*6)+(4*0)+(3*4)+(2*4)+(1*3)=59
59 % 10 = 9
So 1604-43-9 is a valid CAS Registry Number.
