Check Digit Verification of cas no

The CAS Registry Mumber 187039-25-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,7,0,3 and 9 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 187039-25:
(8*1)+(7*8)+(6*7)+(5*0)+(4*3)+(3*9)+(2*2)+(1*5)=154
154 % 10 = 4
So 187039-25-4 is a valid CAS Registry Number.

Synthesis of azasugars via lanthanide-promoted aza Diels-Alder reactions in aqueous solution

Yu, Libing,Li, Jun,Ramirez, Johnny,Chen, Depu,Wang, Peng George

, p. 903 - 907 (1997)

Aqueous aza Diels-Alder reactions of chiral aldehydes, prepared from carbohydrates, with benzylamine hydrochloride and cyclopentadiene, were promoted by lanthanide triflates. The exo/endo selectivities and diastereoselectivities of the reactions were elucidated by NMR, CD spectroscopy, and X-ray crystallography. The nitrogen-containing heterocyclic products were further transformed to azasugars, which are potential inhibitors against glycoprocessing enzymes.
