182567-53-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 182567-53-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,2,5,6 and 7 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 182567-53:
(8*1)+(7*8)+(6*2)+(5*5)+(4*6)+(3*7)+(2*5)+(1*3)=159
159 % 10 = 9
So 182567-53-9 is a valid CAS Registry Number.

Synthesis and alkylation of 3,4-dihydro-1H-1,3-4-benzotriazepine-2,5-diones and related systems
Karp, Gary M.
, p. 1131 - 1135 (2007/10/03)
A synthesis of the 1,3,4-benzotriazepine-2,5-dione 2a and its 2-thio analog 11 is described. The key step was the mild and efficient cyclization of the o-(aminobenzoyl)hydrazine 10, obtained from the reaction of a protected hydrazine derivative with the o
