Check Digit Verification of cas no
The CAS Registry Mumber 782501-07-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,8,2,5,0 and 1 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 782501-07:
(8*7)+(7*8)+(6*2)+(5*5)+(4*0)+(3*1)+(2*0)+(1*7)=159
159 % 10 = 9
So 782501-07-9 is a valid CAS Registry Number.

Enantioselective acylation using a second-generation P-aryl-2- phosphabicyclo[3.3.0]octane catalyst
MacKay, James A.,Vedejs, Edwin
, p. 6934 - 6937 (2007/10/03)
The synthesis of P-aryl-2-phosphabicylco[3.3.0]-octane·HBF 4 salts 3a and 3c is described. Incorporation of the P-3,5-di-tert-butyl-4-methoxyphenyl group in 3c allows use of a less expensive aryl bromide starting material. Deprotonation of the air-stable salts in situ with triethylamine releases the corresponding phosphines 1a and 1c for use in the kinetic resolution of representative secondary alcohols. The method is convenient for small-scale experiments and affords enantioselectivities s close to the values obtained using the free phosphines 1a and 1b in cases where s is ca. 40 or lower.
