138568-41-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 138568-41-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,5,6 and 8 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 138568-41:
(8*1)+(7*3)+(6*8)+(5*5)+(4*6)+(3*8)+(2*4)+(1*1)=159
159 % 10 = 9
So 138568-41-9 is a valid CAS Registry Number.

REACTION OF SEMICYCLIC 1,5-DIKETONES WITH BIS(TRIMETHYLSILOXY)PHOSPHINE
Vysotskii, V. I.,Levan'kov, S. V.
, p. 1196 - 1200 (2007/10/02)
The direction of the reaction of bis(trimethylsiloxy)phosphine with semicyclic 1,5-diketones is essentially a function of the structure of the diketone and yields compounds of the series 2,6-dihydroxyphosphorinane, 2,3-dihydropyranyl-2-phosphinic acid, 1-
