477781-64-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 477781-64-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,7,7,7,8 and 1 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 477781-64:
(8*4)+(7*7)+(6*7)+(5*7)+(4*8)+(3*1)+(2*6)+(1*4)=209
209 % 10 = 9
So 477781-64-9 is a valid CAS Registry Number.

A stereoconvergent synthesis of the C(19)-C(31) fragment of scytophycin C
Yadav,Ahmed
, p. 7147 - 7150 (2007/10/03)
The C(19)-C(31) fragment of the anti-tumor macrolide, scytophycin C, was realized in a stereoconvergent manner utilizing a desymmetrization approach to create eight contiguous asymmetric centers from a common precursor.
