Check Digit Verification of cas no
The CAS Registry Mumber 112438-43-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,2,4,3 and 8 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 112438-43:
(8*1)+(7*1)+(6*2)+(5*4)+(4*3)+(3*8)+(2*4)+(1*3)=94
94 % 10 = 4
So 112438-43-4 is a valid CAS Registry Number.
