89066-57-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 89066-57-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,0,6 and 6 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 89066-57:
(7*8)+(6*9)+(5*0)+(4*6)+(3*6)+(2*5)+(1*7)=169
169 % 10 = 9
So 89066-57-9 is a valid CAS Registry Number.

The Second Generation Synthesis of a Tumor Promoter Pendolmycin
Okabe, Kazuaki,Natsume, Mitsutaka
, p. 7615 - 7624 (2007/10/02)
Total synthesis of a tumor promoter pendolmycin (1) was accomplished in the stereospecific manner using a D-serine derivative 7 and an L-valine derivative 16 as chiral sources.Methyl 2-(bromomethyl)benzoate was used for the critical step of the indole cyc
