162613-90-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 162613-90-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,2,6,1 and 3 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 162613-90:
(8*1)+(7*6)+(6*2)+(5*6)+(4*1)+(3*3)+(2*9)+(1*0)=123
123 % 10 = 3
So 162613-90-3 is a valid CAS Registry Number.

Synthetic study of marine macrolide swinholide A. Stereocontrolled synthesis of the c11-c32 segment
Nakata,Komatsu,Nagasawa
, p. 2403 - 2405 (2007/10/02)
The C24-C32 segment 4 of swinholide A (1) was stereoselectively synthesized starting from (S)-methyl 3-hydroxybutyrate, and the convergent synthesis of the C11-C32 segment 5 was accomplished via stereoselective aldol condensation of 3 and 4.
