49786-25-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 49786-25-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,9,7,8 and 6 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 49786-25:
(7*4)+(6*9)+(5*7)+(4*8)+(3*6)+(2*2)+(1*5)=176
176 % 10 = 6
So 49786-25-6 is a valid CAS Registry Number.

REACTIONS OF ISOCYANATES WITH ETHYL 2-AMINO-1-CYCLOPENTENE-1-CARBOXYLATE
Jensen, Else Marie,Papadopulos, Eleftherios Paul
, p. 2233 - 2235 (2007/10/02)
Aromatic isocyanates react with ethyl 2-amino-1-cyclopentene-1-carboxylate to yield the corresponding ureas, which cyclize by base to 3-substituted 6,7-dihydro 1H-cyclopentapyrimidine-2,4(3H,5H)-diones.
