126181-19-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 126181-19-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,6,1,8 and 1 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 126181-19:
(8*1)+(7*2)+(6*6)+(5*1)+(4*8)+(3*1)+(2*1)+(1*9)=109
109 % 10 = 9
So 126181-19-9 is a valid CAS Registry Number.

NEW SYNTHESIS OF DEHYDRODIPEPTIDES FROM SUBSTITUTED OXAMIC ACIDS
Person, D.,Corre, M. Le
, p. 3069 - 3072 (2007/10/02)
The condensation of phosphorus ylids with t-butyl oxamic esters derived from aminonitriles gives 2-aza 1,3-dienes; subsequent reaction with hydrobromic acid provides protected dehydrodipeptides.
