Check Digit Verification of cas no
The CAS Registry Mumber 666236-28-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,6,6,2,3 and 6 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 666236-28:
(8*6)+(7*6)+(6*6)+(5*2)+(4*3)+(3*6)+(2*2)+(1*8)=178
178 % 10 = 8
So 666236-28-8 is a valid CAS Registry Number.

A new total synthesis of the mycotoxin ochratoxin A (OTA) is presented, in which it is prepared in 9% overall yield from commercially available substrates. The key step consists of the condensation reaction between protected L-phenylalanine and 5-chloro-8-hydroxy-3-methyl-1-oxoisochromane-7-carboxylic acid (ochratoxin α, OTα). The same strategy could be successfully applied to L-d5-phenylalanine, leading to the first total synthesis of d5-OTA, a molecular tracer for the detection and analytical quantification of the natural mycotoxin in food samples by means of stable isotope dilution assay (SIDA).
