Check Digit Verification of cas no
The CAS Registry Mumber 5844-01-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,8,4 and 4 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 5844-01:
(6*5)+(5*8)+(4*4)+(3*4)+(2*0)+(1*1)=99
99 % 10 = 9
So 5844-01-9 is a valid CAS Registry Number.
