127209-16-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 127209-16-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,7,2,0 and 9 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 127209-16:
(8*1)+(7*2)+(6*7)+(5*2)+(4*0)+(3*9)+(2*1)+(1*6)=109
109 % 10 = 9
So 127209-16-9 is a valid CAS Registry Number.

, p. 857 - 862 (2007/10/02)
The Robinson annulation of an octahydroindoloquinolizin-2-one is a general concept for the synthesis of yohimbine alkaloids.Using the phenylsulfonyl group for activation, a diastereoselective synthesis of rac-yohimben-17-one 21 has been developed.A
