1347738-63-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1347738-63-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,4,7,7,3 and 8 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1347738-63:
(9*1)+(8*3)+(7*4)+(6*7)+(5*7)+(4*3)+(3*8)+(2*6)+(1*3)=189
189 % 10 = 9
So 1347738-63-9 is a valid CAS Registry Number.

Formal synthesis of berkelic acid: A lesson in α-alkylation chemistry
McLeod, Michael C.,Wilson, Zoe E.,Brimble, Margaret A.
, p. 400 - 416 (2012/02/15)
The full details of our enantioselective formal synthesis of the biologically active natural product berkelic acid are described. The insertion of the C-18 methyl group proved challenging, with three different approaches investigated to install the correc
