1160163-99-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1160163-99-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,6,0,1,6 and 3 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1160163-99:
(9*1)+(8*1)+(7*6)+(6*0)+(5*1)+(4*6)+(3*3)+(2*9)+(1*9)=124
124 % 10 = 4
So 1160163-99-4 is a valid CAS Registry Number.

Asymmetric total synthesis of pyranicin
Crimmins, Michael T.,Jacobs, Danielle L.
supporting information; experimental part, p. 2695 - 2698 (2009/10/10)
The asymmetric total synthesis of pyranicin (1) is reported. The butenolide ring was constructed via an asymmetric alkylation/ring-closing metathesis strategy. The three stereocenters in the left-hand tetrahydropyran ring were installed by sequential chir
