Check Digit Verification of cas no

The CAS Registry Mumber 128328-78-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,3,2 and 8 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 128328-78:
(8*1)+(7*2)+(6*8)+(5*3)+(4*2)+(3*8)+(2*7)+(1*8)=139
139 % 10 = 9

Synthesis of -yl>ketene S,S-Acetals and Their Reaction with Hydrazine Hydrate

Doelling, Wolfgang,Herrmann, Cornelia,Augustin, Manfred

, p. 927 - 929 (2007/10/02)

The previously unknown ketene S,S-acetals 2, 3, and 4 are prepared by dithiocarboxylation reaction of methylene-active saccharin derivatives 1 in the presence of sodium hydride/carbon disulfide in dry DMF followed by alkylation.Compounds 2a, 3a, and 4a are treated with hydrazine hydrates (85percent) to give 2-hydrazono-3,3-bis(methylthio)propiophenone (6a) and methyl or ethyl pyruvate 6b or 6c, respectively.
