1027201-42-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1027201-42-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,2,7,2,0 and 1 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1027201-42:
(9*1)+(8*0)+(7*2)+(6*7)+(5*2)+(4*0)+(3*1)+(2*4)+(1*2)=88
88 % 10 = 8
So 1027201-42-8 is a valid CAS Registry Number.

[4 + 2]-Annulations of chiral organosilanes: Application to the total synthesis of leucascandrolide A
Su, Qibin,Dakin, Les A.,Panek, James S.
, p. 2 - 24 (2007)
Complete details of an asymmetric synthesis of leucascandrolide A (1) are described. The synthesis highlights the use of two diastereoselective [4 + 2]-annulations for the assembly of the functionalized bispyranyl macrolide 3. An efficient assembly and un
