Check Digit Verification of cas no

The CAS Registry Mumber 138404-34-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,4,0 and 4 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 138404-34:
(8*1)+(7*3)+(6*8)+(5*4)+(4*0)+(3*4)+(2*3)+(1*4)=119

Synthesis of New Functionalized Dichlorophosphines: Precursors od Dicoordinated Phosphorus Heterocycles

Bansal, Raj. K.,Sharma, Dinesh C.,Mahnot, Ruchi

, p. 6433 - 6436 (1991)

Reaction of 3-alkyl-2-aminocycloimmonium salts with PCl3 in presence of NEt3 gives a new class of functionalized dichlorophosphines which undergo dehydrohalogenation intramolecularly to form 1,3,4-diazaphospholo heterocycles.These dichlorophosphines show
