Check Digit Verification of cas no
The CAS Registry Mumber 1818-05-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,8,1 and 8 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1818-05:
(6*1)+(5*8)+(4*1)+(3*8)+(2*0)+(1*5)=79
79 % 10 = 9
So 1818-05-9 is a valid CAS Registry Number.

Preparation of monoalkyl terephthalates: An overview
Chenot, Elodie-Denise,Bernardi, Dan,Comel, Alain,Kirsch, Gilbert
, p. 483 - 490 (2007/10/03)
Terephthalic acid can be readily converted to the corresponding monoalkyl terephthalate in high yield, via a two-step procedure. This method is advantageously compared to the more representative methods described in the literature. The purification of the expected monoester, a crucial problem for this synthetic pathway, is discussed, and an original procedure has been developed. Copyright Taylor & Francis Group, LLC.
