1217890-86-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1217890-86-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,1,7,8,9 and 0 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1217890-86:
(9*1)+(8*2)+(7*1)+(6*7)+(5*8)+(4*9)+(3*0)+(2*8)+(1*6)=172
172 % 10 = 2
So 1217890-86-2 is a valid CAS Registry Number.

The enantioselective total synthesis of nemotin
Jian, Ya-Jun,Wu, Yikang
experimental part, p. 811 - 821 (2010/06/20)
The allene-diyne natural product nemotin was synthesized for the first time through an enantioselective route with the stereogenic center at the lactone moiety derived from l-glutamic acid and the allene axis constructed from the corresponding propargylic
