Check Digit Verification of cas no

The CAS Registry Mumber 1415730-40-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,1,5,7,3 and 0 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1415730-40:
(9*1)+(8*4)+(7*1)+(6*5)+(5*7)+(4*3)+(3*0)+(2*4)+(1*0)=133
133 % 10 = 3
So 1415730-40-3 is a valid CAS Registry Number.

Stereoselectivity of model C22-23 aldol coupling for spirangiens A & B

Gregg, Claire,Perkins, Michael V.

, p. 387 - 394 (2013)

A model system was prepared to investigate the diastereoselectivity of the key C22-23 aldol coupling for the synthesis of spirangiens A & B. The lithium enolate of model ketone 3 was coupled with the differently protected aldehydes 4 (acetonide) and 5 (silyl) giving 3:1 and 3.5:1 dr, respectively, in favour of the unnatural (S) isomer in both cases. The lack of any significant effect on the aldol stereoselectivity induced by the aldehyde protecting groups contrasts with previous literature reports.
