40128-86-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 40128-86-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,0,1,2 and 8 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 40128-86:
(7*4)+(6*0)+(5*1)+(4*2)+(3*8)+(2*8)+(1*6)=87
87 % 10 = 7
So 40128-86-7 is a valid CAS Registry Number.
