160098-39-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 160098-39-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,0,0,9 and 8 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 160098-39:
(8*1)+(7*6)+(6*0)+(5*0)+(4*9)+(3*8)+(2*3)+(1*9)=125
125 % 10 = 5
So 160098-39-5 is a valid CAS Registry Number.
