23623-31-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 23623-31-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,3,6,2 and 3 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 23623-31:
(7*2)+(6*3)+(5*6)+(4*2)+(3*3)+(2*3)+(1*1)=86
86 % 10 = 6
So 23623-31-6 is a valid CAS Registry Number.

BIOSYNTHESIS OF THE 17-MEMBERED CARBOCYCLIC RING OF LANKACIDIN ANTIBIOTICS
Kakinuma, Katsumi,Uzawa, Jun,Uramoto, Masakazu
, p. 5303 - 5306 (2007/10/02)
A mechanism involving contraction of an 18-membered polyketide ring was proposed for the biosynthesis of the 17-membered carbocyclic ring of lankacidin antibiotics based on the feeding experiments of deuterated glycine and (2)H-NMR spectroscopy.
