54102-20-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 54102-20-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,4,1,0 and 2 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 54102-20:
(7*5)+(6*4)+(5*1)+(4*0)+(3*2)+(2*2)+(1*0)=74
74 % 10 = 4
So 54102-20-4 is a valid CAS Registry Number.

2-BENZOPYRILIUM SALTS. 38. A NOVEL VARIANT OF THE CANNIZZARO REACTION
Verin, S. V.,Kuznetsov, E. V.
, p. 866 - 868 (2007/10/02)
1,5-Aldehydoketones (the ring-opened forms of 2-benzopyrylium salts) under the conditions of the Cannizzaro reaction, when intramolecular aldol condensation is not possible, undergo intramolecular disproportionation.
