Check Digit Verification of cas no

The CAS Registry Mumber 134126-91-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,4,1,2 and 6 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 134126-91:
(8*1)+(7*3)+(6*4)+(5*1)+(4*2)+(3*6)+(2*9)+(1*1)=103
103 % 10 = 3
So 134126-91-3 is a valid CAS Registry Number.

FIVE-MEMBERED 2,3-DIOXOHETEROCYCLES XVII. SYNTHESIS AND PROPERTIES OF 2-HYDRAZONO-5-ARYL-2,3-DIHYDRO-3-FURANONES

Zalesov, V. V.,Pulina, N. A.,Andreichikov, Yu. S.

, p. 1746 - 1749 (2007/10/02)

The reaction of 2-benzoylmethylenehydrazono-5-aryl-2,3-dihydro-3-furanones with o-phenylenediamine leads to 2-hydrazono-5-aryl-2,3-dihydro-3-furanones.The latter react with aldehydes and ketones with the formation of substituted 2-hydroxymethylhydrazono-5-aryl-2,3-dihydro-3-furanones, are acylated by 5-aryl-2,3-dihydrofuran-2,3-diones forming 2-aroylpyruvoylhydrazono-5-aryl-2,3-dihydro-3-furanones, and undergo recyclization in an acidic medium to 6-aryl-4-hydroxy-2,3-dihydropyridazin-3-ones.
