160205-68-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 160205-68-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,0,2,0 and 5 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 160205-68:
(8*1)+(7*6)+(6*0)+(5*2)+(4*0)+(3*5)+(2*6)+(1*8)=95
95 % 10 = 5
So 160205-68-5 is a valid CAS Registry Number.
