Check Digit Verification of cas no

The CAS Registry Mumber 17254-09-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,7,2,5 and 4 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 17254-09:
(7*1)+(6*7)+(5*2)+(4*5)+(3*4)+(2*0)+(1*9)=100
100 % 10 = 0
So 17254-09-0 is a valid CAS Registry Number.

Reaction of a Possible Iminoketene Precursor with 6,7-Dialkoxy-1,3-dialkyl-3,4-dihydroisoquinolines

Rastogi, Shri Niwas,Kansal, V. K.,Bhaduri, A. P.

, p. 234 - 237 (2007/10/02)

Reaction of 6,7-dialkoxy-1-alkyl-3,4-dihydro-3-methylisoquinolines (10 - 12) with sulphinamide anhydride (13) yields 2,3-dialkoxy-5,6,7,8-tetrahydro-6-methyl-8-oxoisoquinolinoquinazolines (14 and 19) and 2,3-dialkoxy-13a-alkyl-5,6,7,8,13,13a-hexahydro-6-methyl-8-oxoisoquinolinoquinazolines (15 - 17 and 20).Of the two possible geometrical isomers of the latter class of compounds, the cis-isomer predominates and the trans-isomer is found to be labile towards aerial oxidation.No evidence for the generation of iminoketene (21) is obtained in the reaction of sulphinamide anhydride (13) with various 3,4-dihydroisoquinoline derivatives.
