132555-16-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 132555-16-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,2,5,5 and 5 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 132555-16:
(8*1)+(7*3)+(6*2)+(5*5)+(4*5)+(3*5)+(2*1)+(1*6)=109
109 % 10 = 9
So 132555-16-9 is a valid CAS Registry Number.

Arylation of potassium 2,4-pentanedionate via S(RN)1 on diazosulfides
Dell'Erba,Novi,Petrillo,Tavani,Bellandi
, p. 333 - 342 (2007/10/02)
Potassium 2,4-pentanedionate reacts with diazosulfides (E)-1 and (Z)-2 in DMSO to give 3-aryl-2,4-pentanediones 3 via an S(RN)1 process. Advantages and drawbacks of such new access to 3 are reported together with relevant mechanistic implications.
