Check Digit Verification of cas no

The CAS Registry Mumber 31078-91-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,1,0,7 and 8 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 31078-91:
(7*3)+(6*1)+(5*0)+(4*7)+(3*8)+(2*9)+(1*1)=98
98 % 10 = 8
So 31078-91-8 is a valid CAS Registry Number.

ZUR KENNTNIS DER ORGANOPHOSPHORVERBINDUNGEN XXIII. UEBER ALKENYLSUBSTITUIERTE AMINO-BZW. HALOGENPHOSPHANE UND VERSUCHE ZUM INTRAMOLEKULAREN PHOSPHINIDENABFANG

Diemert, Klaus,Kottwitz, Beatrix,Kuchen, Wilhelm

, p. 307 - 320 (2007/10/02)

Aminophosphanes RP(NEt2)2 and R2P(NEt2), obtained from alkenyl Grignard compounds RMgX (R = -CH=CH2, -CH2CH=CH2, o-(CH2=CH)C6H4-, o-(CH2=CHCH2)C6H4-) and aminochlorophosphanes, reacted smoothly with hydrogen halide to give alkenylhalogenophosphanes RPX2 and R2PX (X = Cl, Br).Properties and reactions of some of these compounds, e.g. with S8, H2O2, H2O and LiAlH4 are reported.On reaction of RPX2 with magnesium only alkenylcyclophosphanes (RP)n were obtained while heterocycles as possible products of an intramolecular reaction of intermediately formed phosphinidenes were not observed.
