127478-99-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 127478-99-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,7,4,7 and 8 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 127478-99:
(8*1)+(7*2)+(6*7)+(5*4)+(4*7)+(3*8)+(2*9)+(1*9)=163
163 % 10 = 3
So 127478-99-3 is a valid CAS Registry Number.

Nouvelle voie d'acces aux alkylidene-3 piperazinediones-2,5
Person, Domonique,le Corre, Maurice
, p. 673 - 676 (2007/10/02)
The synthetic route to 3-alkylidene-2,5-piperazinediones has been studied.The condensation of stabilized phosphorus ylids with 5-substituted-2,3,6-piperazinetriones gives 3-alkylidene-6-substituted-2,5-piperazinediones in good yields.
