Check Digit Verification of cas no
The CAS Registry Mumber 19858-95-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,8,5 and 8 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 19858-95:
(7*1)+(6*9)+(5*8)+(4*5)+(3*8)+(2*9)+(1*5)=168
168 % 10 = 8
So 19858-95-8 is a valid CAS Registry Number.

Reactions of aminals with amides and N-silylated amides of acids containing a three- or four-coordinate phosphorus atom
Pudovik, M.A.,Kibardina, L.K.,Terent'eva, S.A.,Pudovik, A.N.

The reactions of 2-substituted 1,3,2-oxazaphospholidines and 1,3,2-dioxaphospholanes containing an endo- or exo-cyclic secondary amino group with aminals lead to the formation of dimers of cyclic phosphonimidates or phosphinimidates.The products of the reactions of acetylphosphoramidites and bis(trimethylsilyl)phosphoramidites with aminals and N-(alkoxymethyl)dialkylamines are dialkyl P-(aminomethyl)phosphonimidates.
