125657-25-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 125657-25-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,5,6,5 and 7 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 125657-25:
(8*1)+(7*2)+(6*5)+(5*6)+(4*5)+(3*7)+(2*2)+(1*5)=132
132 % 10 = 2
So 125657-25-2 is a valid CAS Registry Number.

REACTIVITY OF CYCLOPENTENYL-ANION ANALOGOUS HETEROCYCLES: SYNTHESIS AND 1,5-ELECTROCYCLISATION OF HOMOPHOSPHOLE

Oebels, Dirk,Klaemer, Frank-Gerrit

, p. 3525 - 3528 (2007/10/02)

The key step of a novel homophosphole synthesis is the reaction of the phospholes 3 with diazomethane in the presence of water leading surprisingly to the oxidized 1,3-dipolar cycloadducts 7.The 1,5-electrocyclization of homophosphole was observed by the racemization of optically active 10c at 120 deg C to be 641 times slower than of homofuran 1a.The activation barrier seems to be largely determined by the barrier of invension at the phosphorus which has to proceed concomitantly.
