Check Digit Verification of cas no

The CAS Registry Mumber 189136-40-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,9,1,3 and 6 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 189136-40:
(8*1)+(7*8)+(6*9)+(5*1)+(4*3)+(3*6)+(2*4)+(1*0)=161
161 % 10 = 1
So 189136-40-1 is a valid CAS Registry Number.

Synthesis of 19-fluororetinal and 20-fluororetinal

Groesbeek, Michel,Smith, Steven O.

, p. 3638 - 3641 (2007/10/03)

We have investigated methods to monofluorinate the methyl positions 19 and 20 in retinal, and we describe a general, mild strategy that proceeds in high yields and is compatible with current carbon-13 labeling strategies. The new sequence consists of the conversion of N-methoxy-N-methylamides via the α-chloromethyl ketone to the corresponding γ-hydroxy nitrile, which can subsequently be fluorinated by (diethylamido)sulfur trifluoride (DAST).
