29138-94-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 29138-94-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,9,1,3 and 8 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 29138-94:
(7*2)+(6*9)+(5*1)+(4*3)+(3*8)+(2*9)+(1*4)=131
131 % 10 = 1
So 29138-94-1 is a valid CAS Registry Number.

Synthesis of alkylbenzenes by Friedl-Crafts reactions catalysed by K10-montmorillonite
Sieskind,Albrecht
, p. 1197 - 1200 (2007/10/02)
Monoalkylation of benzene with primary, secondary and tertiary alcohols took place in high yields when K10-montmorillonite was used as acidic catalyst. Unexpected formation of 1-phenylalkylbenzenes occurred, beside other isomers with primary alcohols. Mon
