1179989-40-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1179989-40-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,7,9,9,8 and 9 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1179989-40:
(9*1)+(8*1)+(7*7)+(6*9)+(5*9)+(4*8)+(3*9)+(2*4)+(1*0)=232
232 % 10 = 2
So 1179989-40-2 is a valid CAS Registry Number.

Stereoselective synthesis of iriomoteolide-1a hemiketal core
Xie, Jun,Horne, David A.
scheme or table, p. 4485 - 4487 (2009/11/30)
A stereoselective synthesis of the cyclic hemiketal core of iriometeolide-1a (1) is described. The key step involves a Sakurai reaction of allylsilane 4 and aldehyde 5, which bears a chiral α-tertiary center. Mild TES deprotection of β,γ-unsaturated keton
