160291-92-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 160291-92-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,0,2,9 and 1 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 160291-92:
(8*1)+(7*6)+(6*0)+(5*2)+(4*9)+(3*1)+(2*9)+(1*2)=119
119 % 10 = 9
So 160291-92-9 is a valid CAS Registry Number.
