1159202-10-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1159202-10-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,5,9,2,0 and 2 respectively; the second part has 2 digits, 1 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1159202-10:
(9*1)+(8*1)+(7*5)+(6*9)+(5*2)+(4*0)+(3*2)+(2*1)+(1*0)=124
124 % 10 = 4
So 1159202-10-4 is a valid CAS Registry Number.

Catechuic acid and ethyl 2,4,5-trihydroxybenzoate from d-glucose
Bhujbal, Namdeo N.,Bande, Omprakash P.,Dhavale, Dilip D.
, p. 734 - 738 (2009)
Synthesis of catechuic acid (1) and ethyl 2,4,5-trihydroxybenzoate (2) from d-glucose-derived β-ketoester is described. The polyhydroxylated β-ketoester obtained from the hydrolysis of sugar β-ketoester 3 was subjected to an aldol-type condensation to get
