Check Digit Verification of cas no
The CAS Registry Mumber 160192-08-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,0,1,9 and 2 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 160192-08:
(8*1)+(7*6)+(6*0)+(5*1)+(4*9)+(3*2)+(2*0)+(1*8)=105
105 % 10 = 5
So 160192-08-5 is a valid CAS Registry Number.
