1344028-46-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1344028-46-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,4,4,0,2 and 8 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1344028-46:
(9*1)+(8*3)+(7*4)+(6*4)+(5*0)+(4*2)+(3*8)+(2*4)+(1*6)=131
131 % 10 = 1
So 1344028-46-1 is a valid CAS Registry Number.

Selepe, Mamoalosi A.,Drewes, Siegfried E.,Van Heerden, Fanie R.
, p. 8654 - 8658 (2011)
The pyranocoumaronochromone lupinalbin H was synthesized in three major steps, which involved preparation of 2′-hydroxygenistein by the Suzuki-Miyaura reaction, followed by oxidative cyclodehydrogenation into lupinalbin A. The final step was the regiospec
