157035-29-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 157035-29-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,7,0,3 and 5 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 157035-29:
(8*1)+(7*5)+(6*7)+(5*0)+(4*3)+(3*5)+(2*2)+(1*9)=125
125 % 10 = 5
So 157035-29-5 is a valid CAS Registry Number.

An Enantioselective Approach to the Synthesis of Manzamine A
Kamenecka, Theodore M.,Overman, Larry E.
, p. 4279 - 4282 (2007/10/02)
A new approach for asymmetric construction of the pyrroloisoquinoline core of manzamine A is described.The synthesis starts with D-(-)-quinic acid and features an intermolecular Mannich reaction as the central step.
