Check Digit Verification of cas no

The CAS Registry Mumber 1399049-71-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,9,9,0,4 and 9 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1399049-71:
(9*1)+(8*3)+(7*9)+(6*9)+(5*0)+(4*4)+(3*9)+(2*7)+(1*1)=208
208 % 10 = 8
So 1399049-71-8 is a valid CAS Registry Number.

Control of reactivity of phosphine imides by intramolecular coordination with an organoboryl group

Kano, Naokazu,Yanaizumi, Kazuhide,Meng, Xiangtai,Kawashima, Takayuki

, p. 429 - 434 (2012/11/07)

Phosphine imides with a boryl substituent 3-5 were synthesized. Their structures were revealed to have a tetracoordinated boron and a phosphorus atom, featuring the N-B coordination by X-ray crystallographic analysis and NMR spectroscopy. The phosphine imide moiety was persistent to hydrolysis, methylation, and the aza-Wittig reaction. The N-B coordination remained intact upon treating with pyridine or fluoride ion. Copyright
