Check Digit Verification of cas no
The CAS Registry Mumber 40928-84-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,0,9,2 and 8 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 40928-84:
(7*4)+(6*0)+(5*9)+(4*2)+(3*8)+(2*8)+(1*4)=125
125 % 10 = 5
So 40928-84-5 is a valid CAS Registry Number.

New Syntheses with Elemental Sulfur. - Synthesis and Reactions of New 1,3,4-Thiadiazoles

The one-step synthesis of 2,5-dialkyl-1,3,4-thiadiazoles 1 from aliphatic aldehydes, hydrazine hydrate and elemental sulfur is described.Chlorination of 1a yields 2,5-bis(trichloromethyl)-1,3,4-thiadiazole (2a).Reaction of 2a with methanol affords the orthoester 3, which forms with aromatic compounds a large number of new 2,5-disubstituted 1,3,4-thiadiazoles 5 - 7.Removal of one trichloromethyl group of 2a leads to 2-trichloromethyl-1,3,4-thiadiazole (10) which on halogenation gives the 2-halo-5-trichloromethyl-1,3,4-thiadiazoles 11.Reactions with nucleophilic compounds lead to the corresponding thiadiazoles 12 and 13.
