Check Digit Verification of cas no
The CAS Registry Mumber 2475-43-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,4,7 and 5 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 2475-43:
(6*2)+(5*4)+(4*7)+(3*5)+(2*4)+(1*3)=86
86 % 10 = 6
So 2475-43-6 is a valid CAS Registry Number.
