128574-75-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 128574-75-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,5,7 and 4 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 128574-75:
(8*1)+(7*2)+(6*8)+(5*5)+(4*7)+(3*4)+(2*7)+(1*5)=154
154 % 10 = 4
So 128574-75-4 is a valid CAS Registry Number.

, p. 529 - 531 (2007/10/03)
The first total synthesis of AB-ring system of an antiproliferative and cytotoxic 9,11-secosterol 1 is described. Enantiomerically pure (3S,5S,6S,10S)-3,6-diacetoxy-10-methylbicyclo[4.4.0]decan-9-one8 (steroidal numeration) was prepared from (S)-Wieland-Miescher ketone.
