35994-55-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 35994-55-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,5,9,9 and 4 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 35994-55:
(7*3)+(6*5)+(5*9)+(4*9)+(3*4)+(2*5)+(1*5)=159
159 % 10 = 9
So 35994-55-9 is a valid CAS Registry Number.

FLEXIBLE SYNTHETIC ROUTE TO 6-DEOXY AND 11-DEOXYANTHRACYCLINONES
Angelucci, F.,Barchielli, G.,Brussani, G. A.,Gigli, M.,Gioia, B.,et. al.
, p. 5693 - 5696 (2007/10/02)
The regiospecific synthesis of 6-deoxydaunomycinone 3 and 1-hydroxy-4-demethoxy-11-deoxydaunomycinone 4 is reported: the route allows the preparation of 6-deoxy or 11-deoxyanthracyclinones through the γ or δ lactones 6 and 11.
