160238-90-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 160238-90-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,0,2,3 and 8 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 160238-90:
(8*1)+(7*6)+(6*0)+(5*2)+(4*3)+(3*8)+(2*9)+(1*0)=114
114 % 10 = 4
So 160238-90-4 is a valid CAS Registry Number.

FACILE CONSTRUCTION OF MEDIUM-SIZED CARBOCYCLES, TOTAL SYNTHESIS OF (+/-)-PARVIFOLINE
Grimm, Erich L.,Levac, Sylvain,Coutu, Michel L.
, p. 501 - 502 (2007/10/02)
A new synthetic approach to medium-sized rings has been accomplished via intramolecular cyclization of a sulfone-stabilized carbanion.This strategy was applied to the total synthesis of (+/-)-parvifoline.
