Calculate Digit Verification of CAS Registry Number 130412-98:
(8*1)+(7*3)+(6*0)+(5*4)+(4*1)+(3*2)+(2*9)+(1*8)=85
85 % 10 = 5
So 130412-98-5 is a valid CAS Registry Number.

1-(Triphenylphosphorylideneaminomethyl)benzotriazole (BETMIP) a Novel +CH2N= Synthetic Equivalent: Its Application to the Synthesis of Carbodiimides, Imines, Isothiocyanates, Aziridines, and Secondary Amines

Katritzky, Alan R.,Jiang, Jinglong,Urogdi, Laszlo

, p. 565 - 567 (1990)

One-carbon homologation has been achieved in novel syntheses of the title compounds by one-pot reaction of 1-(triphenylphosphorylideneaminomethyl)benzotriazole (1) with Grignard reagents followed by in situ transformations of the phosphorazene functionality with isocyanates, aldehydes, carbon disulfide, ethylene oxide, and alkyl halides, respectively.
