1323141-89-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1323141-89-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,2,3,1,4 and 1 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1323141-89:
(9*1)+(8*3)+(7*2)+(6*3)+(5*1)+(4*4)+(3*1)+(2*8)+(1*9)=114
114 % 10 = 4
So 1323141-89-4 is a valid CAS Registry Number.

Multicomponent cascade reactions for the synthesis of 2,3-dihydrobenzofuran derivatives
Li, Qu-Bo,Hu, Xiao-Chun
supporting information, p. 1633 - 1635 (2013/02/23)
A multicomponent cascade reaction for the synthesis of highly substituted 2,3-dihydrobenzofuran derivatives with moderate to good yields was developed. The synthetic utilities of these 2,3-dihydrobenzofurans were also further explored. Ethyl 2-hydroxy-3-o
