Check Digit Verification of cas no

The CAS Registry Mumber 141738-98-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,1,7,3 and 8 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 141738-98:
(8*1)+(7*4)+(6*1)+(5*7)+(4*3)+(3*8)+(2*9)+(1*8)=139
139 % 10 = 9
So 141738-98-9 is a valid CAS Registry Number.

, p. 671 - 678 (2007/10/02)

The synthesis of the title compound is described.It may be stabilised by the reaction of its tetramer with BF3.The tetramer displays several isomers and conformers in solution; one of them has been isolated and its crystal structure determined.The crystal structure of the 2-N-BF3 complex of the parent 4,5-diisopropyl-1,2,3,4-triazaphosphole has also been obtained.
