Check Digit Verification of cas no

The CAS Registry Mumber 857030-20-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,7,0,3 and 0 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 857030-20:
(8*8)+(7*5)+(6*7)+(5*0)+(4*3)+(3*0)+(2*2)+(1*0)=157
157 % 10 = 7
So 857030-20-7 is a valid CAS Registry Number.

The rapid preparation of 2-aminosulfonamide-1,3,4-oxadiazoles using polymer-supported reagents and microwave heating

Baxendale, Ian R.,Ley, Steven V.,Martinelli, Marisa

, p. 5323 - 5349 (2007/10/03)

Herein, we report on the preparation of a library of 5-substituted-2-amino- 1,3,4-oxadiazoles and the corresponding thiadiazole analogues. Presented is a one-pot preparation of the 2-aminosulfonylated analogues through a three component coupling of an acylhydrazine, an isocyanate and sulfonyl chloride promoted by a polymer-supported phosphazine base under microwave dielectric heating. Also described is the optimization process and details pertaining to the elucidation of the reaction products.
