158548-99-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 158548-99-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,8,5,4 and 8 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 158548-99:
(8*1)+(7*5)+(6*8)+(5*5)+(4*4)+(3*8)+(2*9)+(1*9)=183
183 % 10 = 3
So 158548-99-3 is a valid CAS Registry Number.

The diastereoselective synthesis of (+)-actinobolin from D-glucose
Ward,Kaller
, p. 407 - 410 (2007/10/02)
The carbocyclic ring of actinobolin was constructed by a [3 + 3] annulation of a D-galactosamine derivative with 3-phenylthio-2-(trimethylsilylmethyl)propene. Formation of the lactone and acylation with L-alanine according to literature precedent gave (+)
