Check Digit Verification of cas no
The CAS Registry Mumber 1188-22-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,1,8 and 8 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1188-22:
(6*1)+(5*1)+(4*8)+(3*8)+(2*2)+(1*2)=73
73 % 10 = 3
So 1188-22-3 is a valid CAS Registry Number.

BH3-catalyzed oligomerization of ethyl diazoacetate: The role of C-boron enolates
Bai, Jie,Burke, Lonnie D.,Shea, Kenneth J.
, p. 4981 - 4991 (2007)
In contrast to trialkyl boranes, the reaction of borane (BH3) and ethyl diazoacetate (EDA) generates dimer, trimer, and oligomers of EDA. The products arise from double, triple, and multiple insertions of CHCO 2Et groups in B-C bonds. On the basis of NMR spectroscopic data, trapping experiments, and computational studies, a novel C-boron enolate has been identified as a key intermediate in this reaction. This C-boron enolate species is calculated to be 7.1 kcal/mol (gas phase) more stable than its isomeric O-boron enolate form. Both spectroscopic data and trapping results also reveal the formation of a doubly borylated enolate generated as a side product by a proton transfer between the C- and O-boron monoenolates.
