Check Digit Verification of cas no
The CAS Registry Mumber 40891-99-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,0,8,9 and 1 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 40891-99:
(7*4)+(6*0)+(5*8)+(4*9)+(3*1)+(2*9)+(1*9)=134
134 % 10 = 4
So 40891-99-4 is a valid CAS Registry Number.
