97747-36-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 97747-36-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,7,7,4 and 7 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 97747-36:
(7*9)+(6*7)+(5*7)+(4*4)+(3*7)+(2*3)+(1*6)=189
189 % 10 = 9
So 97747-36-9 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.
