Check Digit Verification of cas no

The CAS Registry Mumber 1242059-34-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,4,2,0,5 and 9 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1242059-34:
(9*1)+(8*2)+(7*4)+(6*2)+(5*0)+(4*5)+(3*9)+(2*3)+(1*4)=122
122 % 10 = 2
So 1242059-34-2 is a valid CAS Registry Number.

Envirocat EPZ-10: A solid acid catalyst for the synthesis of 1,8-dioxo-octahydroxanthenes in aqueous medium

Pore,Shaikh,Patil,Dongare,Desai

, p. 2215 - 2219 (2010)

An efficient method for synthesis of 1,8-dioxo-octahydroxanthenes using EPZ-10 as a heterogeneous catalyst is developed. In this method, aldehydes and dimedone/cyclohexane-1,3-dione are heated at 70C in the presence of a catalytic amount of EPZ-10 in wate
