40416-27-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 40416-27-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,0,4,1 and 6 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 40416-27:
(7*4)+(6*0)+(5*4)+(4*1)+(3*6)+(2*2)+(1*7)=81
81 % 10 = 1
So 40416-27-1 is a valid CAS Registry Number.
