Check Digit Verification of cas no

The CAS Registry Mumber 80741-54-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,0,7,4 and 1 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 80741-54:
(7*8)+(6*0)+(5*7)+(4*4)+(3*1)+(2*5)+(1*4)=124
124 % 10 = 4
So 80741-54-4 is a valid CAS Registry Number.

An Efficient Synthesis of Heterocyclic Analogs of 1-Arylnaphthalene Lignans

Kuroda, Tooru,Takahashi, Masami,Ogiku, Tsuyoshi,Ohmizu, Hiroshi,Nishitani, Takashi,et al.

, p. 7353 - 7357 (2007/10/02)

The heterocyclic analogs 5a-f, 16, and 20 of 1-arylnaphthalene lignans were synthesized by Diels-Alder reactions of acetoxy aldehydes 11a-f, 14, and 18 with dimethyl acetylenedicarboxylate.A pathway for formation of 5a-f, 16, and 20 through the intermediacy of heteroaromatic isobenzofurans derived from acetoxy aldehydes is discussed.
