87702-54-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 87702-54-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,7,7,0 and 2 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 87702-54:
(7*8)+(6*7)+(5*7)+(4*0)+(3*2)+(2*5)+(1*4)=153
153 % 10 = 3
So 87702-54-3 is a valid CAS Registry Number.

STUDIES IN MACROLIDE SYNTHESIS: AN EFFICIENT SYNTHESIS OF TWO CHIRAL FRAGMENTS OF ERYTHRONOLIDE A
Paterson, Ian,Patel, Shailesh K.,Porter, John R.
, p. 3395 - 3396 (2007/10/02)
An efficient asymmetric synthesis of the C1-C5 fragment (3) together with the epimeric C7-C11 fragment (4) used in the Stork approach to the synthesis of erythronolide A is described.
