1161082-91-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1161082-91-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,6,1,0,8 and 2 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1161082-91:
(9*1)+(8*1)+(7*6)+(6*1)+(5*0)+(4*8)+(3*2)+(2*9)+(1*1)=122
122 % 10 = 2
So 1161082-91-2 is a valid CAS Registry Number.

Claisen ring expansion approach toward the CDEF ring system of lancifodilactone G
Paquette, Leo A.,Lai, Kwong Wah
scheme or table, p. 299 - 302 (2009/12/03)
The fused CDEF ring system of lancifodilactone G is assembled via a Nozaki-Hiyama-Kishi cross-coupling reaction and a Petasis-Claisen ring expansion sequence as the key strategic steps.
