112138-80-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 112138-80-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,2,1,3 and 8 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 112138-80:
(8*1)+(7*1)+(6*2)+(5*1)+(4*3)+(3*8)+(2*8)+(1*0)=84
84 % 10 = 4
So 112138-80-4 is a valid CAS Registry Number.

3-Acyltetramic acid antibiotics. 2. Synthesis of (+)-streptolic acid
Ireland,Smith
, p. 854 - 860 (2007/10/02)
An efficient synthesis of streptolic acid, a product obtained from cleavage of the antibiotic streptolydigin, is described. The approach is based on the use of D-( plus )-glucose for the source of absolute stereochemistry, and the transfer of asymmetry is
