195141-40-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 195141-40-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,5,1,4 and 1 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 195141-40:
(8*1)+(7*9)+(6*5)+(5*1)+(4*4)+(3*1)+(2*4)+(1*0)=133
133 % 10 = 3
So 195141-40-3 is a valid CAS Registry Number.

Synthesis of (+)-(1S,2S,5R,6S)-1-Hydroxysamin from L-(+)-Arabinose
Yamauchi, Satoshi,Kinoshita, Yoshiro
, p. 1342 - 1348 (2007/10/03)
As a model for the synthesis of optically active 6-aryl-2-aryloxy-1-hydroxy-3,7-dioxabicyclo-[3.3.0]octanes, which are 1,2-dioxygenated furofuran lignans, the most important intermediate, (+)-(1S,2S,5R,6S)-1-hydroxysamin (1), was synthesized from L-(+)-ar
