161040-09-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 161040-09-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,1,0,4 and 0 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 161040-09:
(8*1)+(7*6)+(6*1)+(5*0)+(4*4)+(3*0)+(2*0)+(1*9)=81
81 % 10 = 1
So 161040-09-1 is a valid CAS Registry Number.
