192181-39-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 192181-39-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,2,1,8 and 1 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 192181-39:
(8*1)+(7*9)+(6*2)+(5*1)+(4*8)+(3*1)+(2*3)+(1*9)=138
138 % 10 = 8
So 192181-39-8 is a valid CAS Registry Number.

Concise synthesis of (4S,5S)-4,5-(isopropylidenedioxy)-2-cyclopentenone and a novel C2-symmetric ketone

Armstrong, Alan,Hayter, Barry R.

, p. 1677 - 1684 (1997)

A new and concise synthesis of the useful synthetic intermediate 1 is described which also allows access to a novel C2-symmetric ketone 2. The route relies on the Sharpless asymmetric dihydroxylation of fulvenes.
