Check Digit Verification of cas no

The CAS Registry Mumber 309241-55-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,0,9,2,4 and 1 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 309241-55:
(8*3)+(7*0)+(6*9)+(5*2)+(4*4)+(3*1)+(2*5)+(1*5)=122
122 % 10 = 2
So 309241-55-2 is a valid CAS Registry Number.

Towards the synthesis of amphidinolide B. An intramolecular stille coupling approach

Belen Cid,Pattenden

, p. 7373 - 7378 (2000)

A synthetic approach towards the cytotoxic polyene polyol macrolide amphidinolide B (1), based on elaboration of the C1-C13 carboxylic acid 4. and the C14-C25 alcohol 3 units, their esterification to the iodostannyl ester 2, and an intramolecular Stille sp2-sp2 coupling reaction, is described. In spite of adequate precedent and model experiments, circumstances conspired and the aforementioned coupling reaction was not realised in this case. (C) 2000 Elsevier Science Ltd.
