Check Digit Verification of cas no

The CAS Registry Mumber 192815-80-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,2,8,1 and 5 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 192815-80:
(8*1)+(7*9)+(6*2)+(5*8)+(4*1)+(3*5)+(2*8)+(1*0)=158
158 % 10 = 8
So 192815-80-8 is a valid CAS Registry Number.

Cycloadditions of 1,3-oxazolium-4-olates (Isomunchnones) by Rhodium(II)-Induced decomposition of α-Diazocarbonyl derivatives of (5R)- and (5S)-phenyloxazin-3-one as a chiral template

Angell, Richard,Fengler-Veith, Marion,Finch, Harry,Harwood, Laurence M.,Tucker, Toby T.

, p. 4517 - 4520 (2007/10/03)

Cycloadducts (6-9) were synthesised from isomunchnone derivatives of (5R)- and (5S)-phenyloxazin-3-one by rhodium(II)-catalysed decomposition of α-diazocompounds (3a-c). Additions to various carbon-carbon dipolarophiles proceeded with high endo/exo-selectivities and moderate diastereofacial selectivities.
