135311-70-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 135311-70-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,5,3,1 and 1 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 135311-70:
(8*1)+(7*3)+(6*5)+(5*3)+(4*1)+(3*1)+(2*7)+(1*0)=95
95 % 10 = 5
So 135311-70-5 is a valid CAS Registry Number.

Chemistry of novel compounds with multifunctional carbon structure. 8. Application of the α-cyano-α-fluorophenylacetic acid (CFPA) method to the enantiomeric excess determination of some hindered alcohols in asymmetric and natural product syntheses

Takeuchi,Itoh,Kawahara,Koizumi

, p. 1861 - 1870 (2007/10/02)

The reaction of CFPA chloride (2b) with pinacolyl alcohol was found to proceed more than 500 times faster than that of MTPA chloride (1b) suggesting that the CFPA method induces potentially much less kinetic resolution than the widely used MTPA method in

α-cyano-α-fluorophenylacetic acid (CFPA): A new reagent for determining enantiomeric excess that gives very large 19F NMR Δδ values
