158251-57-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 158251-57-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,8,2,5 and 1 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 158251-57:
(8*1)+(7*5)+(6*8)+(5*2)+(4*5)+(3*1)+(2*5)+(1*7)=141
141 % 10 = 1
So 158251-57-1 is a valid CAS Registry Number.

Intermediates for tricyclic benzodiazepines

-

, (2008/06/13)

Tricyclic benzodiazepine derivatives ("A") bearing a hydroxylower alkyl substituent in the 1-position and a heterocyclic ring joined between positions 4 and 5 of the benzodiazepine moiety are described. The heterocyclic ring will contain the nitrogen atom appearing at position 4 of the benzodiazepine ring as well as the hetero atom, which may be either oxygen or nitrogen, attached to the carbon atom at the 5-position of the benzodiazepine ring. "A" bearing an oxygen atom in the new heterocyclic ring may be formed from the corresponding 4,5-unsaturated benzodiazepines by treatment with an epoxide compound in the presence of an acid catalyst. "A" bearing either a nitrogen or an oxygen atom in the new heterocyclic ring may be prepared by cyclization of the corresponding open compound. "A" are useful as sedative, muscle relaxant and anti-convulsant agents.
