122552-72-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 122552-72-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,2,5,5 and 2 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 122552-72:
(8*1)+(7*2)+(6*2)+(5*5)+(4*5)+(3*2)+(2*7)+(1*2)=101
101 % 10 = 1
So 122552-72-1 is a valid CAS Registry Number.

SYNTHETIC STUDIES ON OPHIOBOLINS
Rowley, Michael,Kishi, Yoshito
, p. 4909 - 4912 (2007/10/02)
The tricyclic ketone 14, an ophiobolin analogue lacking only the C-ring side chain, was synthesized in optically active form; the key step was the intramolecular NiCl2/CrCl2 mediated coupling of 10 to yield 11.
