Check Digit Verification of cas no

The CAS Registry Mumber 91813-49-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,8,1 and 3 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 91813-49:
(7*9)+(6*1)+(5*8)+(4*1)+(3*3)+(2*4)+(1*9)=139
139 % 10 = 9
So 91813-49-9 is a valid CAS Registry Number.

STEREOCHEMICAL STUDIES -- 79 SYNTHESIS AND KINETIC STUDY ON THE RETRODIENE DECOMPOSITION OF NORBORNENE-CONDENSED 1,3-OXAZIN-4-ONES

Stajer, Geza,Mod, Laszlo,Szabo, Angela E.,Fueloep, Ferenc,Bernath, Gabor,Sohar, Pal

, p. 2385 - 2393 (2007/10/02)

The cis-exo-amino acid 3 with norbornene skeleton was converted into 2-aryl-cis-exo-1,3-oxazin-4-ones 5a-d.These compounds, similarly to the diendo isomers 1a-d studied by us earlier, undergo retrodiene decomposition under mild conditions to give 2-aryl-6
