Check Digit Verification of cas no

The CAS Registry Mumber 1262285-78-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,2,2,8 and 5 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1262285-78:
(9*1)+(8*2)+(7*6)+(6*2)+(5*2)+(4*8)+(3*5)+(2*7)+(1*8)=158
158 % 10 = 8
So 1262285-78-8 is a valid CAS Registry Number.

Synthesis and spectral characterization of 2-(substituted)-1,3, 2λ5-oxazaphosphinan-2-ones/-2-thiones

Venkateswarlu,Satyanarayana,Rao, C. V. Nageswara,Raju, C. Naga

scheme or table, p. 1273 - 1277 (2011/12/15)

2-(Substituted)-1,3,2λ5-oxazaphosphinan-2-ones/-2-thiones (3-10) were synthesized in a two step process. Condensation of equimolar quantities of 3-aminopropanol (1) with phosphorous oxychloride/thiophosphoryl chloride in dry THF in presence of Et3N to afford the corresponding intermediate 2-chloro-1,3,2λ5-oxazaphosphinan-2-one/-2-thione (2). In the next step 2 reacted in situ with various phenols and aromatic amines in dry THF and TEA to obtain the title compounds. Analytical data, IR, 1H, 13C, 31P and Mass spectral data have been discussed and supported all the structures.
