131969-00-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 131969-00-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,1,9,6 and 9 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 131969-00:
(8*1)+(7*3)+(6*1)+(5*9)+(4*6)+(3*9)+(2*0)+(1*0)=131
131 % 10 = 1
So 131969-00-1 is a valid CAS Registry Number.

Synthesis of L and D α-amino acids from chiral amidals
Amoroso, Rosa,Cardillo, Giuliana,Tomasini, Claudia
, p. 6412 - 6416 (1990)
A new synthesis of D- and L-alanine is described, by means of the mercury cyclisation of the chiral amidal obtained from the reaction of 1,3,5-tri-(S)-phenylethylhexahydrotriazine and acryloyl chloride.
