Check Digit Verification of cas no

The CAS Registry Mumber 1572246-83-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,5,7,2,2,4 and 6 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1572246-83:
(9*1)+(8*5)+(7*7)+(6*2)+(5*2)+(4*4)+(3*6)+(2*8)+(1*3)=173
173 % 10 = 3
So 1572246-83-3 is a valid CAS Registry Number.

Access to enantiopure 4-substituted 1,5-aminoalcohols from phenylglycinol-derived δ-lactams: Synthesis of Haliclona alkaloids

Amat, Mercedes,Guignard, Guillaume,Llor, Nuria,Bosch, Joan

, p. 2792 - 2802 (2014/04/17)

LiNH2BH3-promoted reductive opening of 8-substituted phenylglycinol-derived oxazolopiperidone lactams leads to enantiopure 4-substituted-5-aminopentanols, which are used as starting building blocks in the synthesis of the Haliclona alkaloids haliclorensin C, haliclorensin, and halitulin (formal). The starting lactams are easily accessible by a cyclocondensation reaction of (R)-phenylglycinol with racemic γ-subtituted δ-oxoesters, in a process that involves a dynamic kinetic resolution.
