2059-40-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 2059-40-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,0,5 and 9 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 2059-40:
(6*2)+(5*0)+(4*5)+(3*9)+(2*4)+(1*0)=67
67 % 10 = 7
So 2059-40-7 is a valid CAS Registry Number.
