Check Digit Verification of cas no

The CAS Registry Mumber 94243-45-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,4,2,4 and 3 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 94243-45:
(7*9)+(6*4)+(5*2)+(4*4)+(3*3)+(2*4)+(1*5)=135
135 % 10 = 5
So 94243-45-5 is a valid CAS Registry Number.

Spirocyclopropane compounds. V. One-step synthesis of 5-acetyl-spiro[benzofuran-2(3H),1'-cyclopropan]-3-one

Watanabe,Kawada,Takamoto,et al.

, p. 3373 - 3377 (1984)

5-Acetylspiro[benzofuran-2(3H),1'-cyclopropan]-3-one (3a, AG-629), previously found to be the most potent antiulcer compound in a series of spirocyclopropanes, was obtained by one step synthesis starting from methyl 5-acetyl-2-[(tetrahydro-2-oxo-3-furanyl)oxy]benzoate (1a). In this reaction, 5,10'-(diacetyl-5',6'-dihydrospiro[benzofuran-2(3H),4'(3'H)-[2H]oxocino[3, 2-b]-benzofuran]-3-one (5a), which has a new ring system, and 1H,3H-8-acetyl-4,5-dihydro-naphtho[1,2-c:4,3-b']difuran-1-one (6) were isolated as by-products. A possible reaction mechanism is presented.
