102663-91-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 102663-91-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,2,6,6 and 3 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 102663-91:
(8*1)+(7*0)+(6*2)+(5*6)+(4*6)+(3*3)+(2*9)+(1*1)=102
102 % 10 = 2
So 102663-91-2 is a valid CAS Registry Number.

Hydroxy-2-styrylchromones 5a-i were prepared by debenzylation of benzyloxy-2-styrylchromones 3a-i, which were synthesised by the Baker-Venkataraman method. The last step of this method, the cyclodehydration 5-aryl-3-hydroxy-1-(2-hydroxyaryl)-2,4-pentadien
