4723-24-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 4723-24-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,7,2 and 3 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 4723-24:
(6*4)+(5*7)+(4*2)+(3*3)+(2*2)+(1*4)=84
84 % 10 = 4
So 4723-24-4 is a valid CAS Registry Number.

Synthesis and reactivity of chiral pentavalent bismuth derivatives
Finet,Fedorov
, p. 1488 - 1495 (2007/10/03)
Eight new pentavalent organobismuth derivatives were synthesized by the reactions of triphenylbismuth or phenyl-2,2"-biphenylenebismuth with chiral (1R)-(-)-camphor-10-sulfonic, (-)-menthyloxyacetic, or (R)-3-phenylbutyric acids. Enantioselective C-arylat
