3850-43-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 3850-43-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,8,5 and 0 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 3850-43:
(6*3)+(5*8)+(4*5)+(3*0)+(2*4)+(1*3)=89
89 % 10 = 9
So 3850-43-9 is a valid CAS Registry Number.
