187239-91-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 187239-91-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,7,2,3 and 9 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 187239-91:
(8*1)+(7*8)+(6*7)+(5*2)+(4*3)+(3*9)+(2*9)+(1*1)=174
174 % 10 = 4
So 187239-91-4 is a valid CAS Registry Number.

Studies in macrolide synthesis: A novel cyclodimerisation approach to the synthesis of elaiophylin using a double stille cross-coupling reaction
Paterson, Ian,Man, Jocelyn
, p. 695 - 698 (2007/10/03)
The 16-membered macrodiolide 4, corresponding to the macrocyclic core of elaiophylin (1), was prepared via the copper-mediated cyclodimerisation of stannane 3.
