Check Digit Verification of cas no

The CAS Registry Mumber 887258-85-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,8,7,2,5 and 8 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 887258-85:
(8*8)+(7*8)+(6*7)+(5*2)+(4*5)+(3*8)+(2*8)+(1*5)=237
237 % 10 = 7
So 887258-85-7 is a valid CAS Registry Number.

Synthesis and characterization of a new chromanoisoxazole

Murthy,Nanda, Rani,Kumar, K. Ravi,Swamy

, p. 532 - 534 (2007/10/03)

The synthesis of a new chromanoisoxazole 4 has been reported. Acylation of resorcinol using anhyd. ZnCl2 and gl. acetic acid affords resacetophenone, which on nuclear prenylation with isoprene/PPA/xylene gives chroman 2. Compound 2 on treatment with p-chlorobenzaldehyde/ ethanol/KOH yields a chalcone 3. The product 3 on further treatment with hydroxylamine hydrochloride results in the formation of the chromanoisoxazole 4. The structure of 4 has been characterized by spectroscopic and crystallographic techniques.
