127718-80-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 127718-80-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,7,7,1 and 8 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 127718-80:
(8*1)+(7*2)+(6*7)+(5*7)+(4*1)+(3*8)+(2*8)+(1*0)=143
143 % 10 = 3
So 127718-80-3 is a valid CAS Registry Number.

A novel stereoselective synthesis of the ring AB podocarpate system
Lu,Shoemaker,Wheeler
, p. 6993 - 6996 (2007/10/02)
A new way of stereoselectively synthesizing rings A and B of podocarpate has been developed; the correct stereochemistry at C4 is obtained during a cyclization linking C2 to C3.
