100242-07-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 100242-07-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,0,2,4 and 2 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 100242-07:
(8*1)+(7*0)+(6*0)+(5*2)+(4*4)+(3*2)+(2*0)+(1*7)=47
47 % 10 = 7
So 100242-07-7 is a valid CAS Registry Number.

Dehydro keto methylene and keto methylene analogues of substance P. Synthesis and biological activity

Ewenson,Laufer,Chorev,Selinger,Gilon

, p. 416 - 421 (2007/10/02)

The synthesis of dehydro keto methylene and keto methylene analogues of substance P using classical peptide synthesis is described. The following analogues were prepared: [pGlu6,Gly9ψ(COCH2)(RS)Leu10]SP6-11

Derivatives of the potent angiotensin converting enzyme inhibotor 5(S)-benzamido-4-oxo-6-phenylhexanoyl-L-proline: Effect of changes at positions 2 and 5 of the hexanoic acid portion

Almquist,Crase,Jennings-White,Meyer,Hoefle,Smith,Essenburg,Kaplan

, p. 1292 - 1299 (2007/10/02)

Several derivatives of the potent angiotensin converting enzyme inhibitor 5(S)-benzamido-4-oxo-6-phenylhexanoyl-L-proline (1) were synthesized and tested for converting enzyme inhibition activity and blood pressure lowering effects in rats. One compound, 5(S)-benzamido-2(R)-methyl-4-oxo-6-phenylhexanoyl-L-proline (2a), had an I50 against angiotensin converting enzyme of 1.0 x 10-9 M and is the most potent inhibitor prepared thus far in this class of compounds. Testing of 2a orally at 30 mg/kg for inhibition of the angiotensin I induced blood pressure increase in conscious normotensive rats gave 100% inhibition that required 143 min before the angiotensin I blood pressure response returned to 70% of the pretreatment control response. In the conscious renal hypertensive rat, 2a given orally at a dose of 3 mg/kg caused a lowering of blood pressure that reached its maximum of 40 mmHg 8 h following drug administration.
