340185-23-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 340185-23-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,4,0,1,8 and 5 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 340185-23:
(8*3)+(7*4)+(6*0)+(5*1)+(4*8)+(3*5)+(2*2)+(1*3)=111
111 % 10 = 1
So 340185-23-1 is a valid CAS Registry Number.

Tietze, Lutz F.
, p. 901 - 902 (2007/10/03)
Three building blocks are coupled convergently in the first total synthesis of the macrolide antibiotic 5,6-tetrahydrocineromycin B (1): the facial selective allylation of a methyl ketone is the key step of the synthesis. TBDMS = tert-bytyldimethylsilyl,
