Check Digit Verification of cas no

The CAS Registry Mumber 175358-83-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,5,3,5 and 8 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 175358-83:
(8*1)+(7*7)+(6*5)+(5*3)+(4*5)+(3*8)+(2*8)+(1*3)=165
165 % 10 = 5
So 175358-83-5 is a valid CAS Registry Number.

Synthesis of defucogilvocarcin V isosteres via MAD-mediated conjugate addition of carbanions to naphthoquinone ketals

Hart, David J.,Mannino, Anthony

, p. 3841 - 3856 (1996)

Treatment of a complex between naphthoquinone ketal 7 and methylaluminum bis(2,6-di-tert-butyl-4-methylphenoxide (MAD) with aryllithium reagents prepared by metallation of oxazoline 13 and amide 18, gave conjugate adducts which were converted to defucogilvocarcin V analogs 2 and 3 via a short reaction sequence. Some problems encountered in the metallation of oxazoline 19, a structural analog of amide 18, are also described.
