Check Digit Verification of cas no
The CAS Registry Mumber 203730-54-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,3,7,3 and 0 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 203730-54:
(8*2)+(7*0)+(6*3)+(5*7)+(4*3)+(3*0)+(2*5)+(1*4)=95
95 % 10 = 5
So 203730-54-5 is a valid CAS Registry Number.

A number of 2-N-alkylamino- or 2-N-phenylamino-, 2-N,N-dialkylamino-, and 2-N-alkyl-N-phenylaminothiophenes have been prepared in good yields by adding a solution of tert-butylalcohol and potassium tert-butoxide in dimethylsulfoxide to a solution of the adduct from a lithiated 1-alkyne, RCH2C≡CLi, or the lithiated allene, tBuCH=C=CHLi, and isothiocyanate, R′N=C=S, in tetrahydrofuran and subsequently hydrolyzing the reaction mixture or quenching it with methyl iodide.
