55168-29-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 55168-29-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,5,1,6 and 8 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 55168-29:
(7*5)+(6*5)+(5*1)+(4*6)+(3*8)+(2*2)+(1*9)=131
131 % 10 = 1
So 55168-29-1 is a valid CAS Registry Number.

Catalytic hydrogenation of the benzotripyranone 3 yields the hexahydrobenzotripyrans 5 and 6, while ring closure reactions of the 1,2,4-benzenetriyltris(3-oxypropionic acid) 16c and catalytic hydrogenation lead to the less symmetric isomers 21 and 12.
