Check Digit Verification of cas no

The CAS Registry Mumber 192879-21-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,2,8,7 and 9 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 192879-21:
(8*1)+(7*9)+(6*2)+(5*8)+(4*7)+(3*9)+(2*2)+(1*1)=183
183 % 10 = 3
So 192879-21-3 is a valid CAS Registry Number.

A new type of plant activator: Synthesis of thieno[2,3-d][1,2,3]-thiadiazole-6-carboxylic acid derivatives via Hurd-Mori cyclization

Stanetty, Peter,Kremslehner, Manfred,Voellenkle, Horst

, p. 853 - 856 (2007/10/03)

We present a short and efficient synthesis of the title compounds starting with cheap and readily available methylenebutanedioic acid and thioacetic acid. The optimised sequence allows the large-scale preparation of this new type of plant activator in a few steps. ortho-Lithiation is used for the introduction of substituents into the 5-position. A modified reaction mechanism for the Hurd-Mori reaction is suggested to explain the unexpected aromatisation.
