123475-40-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 123475-40-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,3,4,7 and 5 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 123475-40:
(8*1)+(7*2)+(6*3)+(5*4)+(4*7)+(3*5)+(2*4)+(1*0)=111
111 % 10 = 1
So 123475-40-1 is a valid CAS Registry Number.
