Check Digit Verification of cas no
The CAS Registry Mumber 162147-18-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,2,1,4 and 7 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 162147-18:
(8*1)+(7*6)+(6*2)+(5*1)+(4*4)+(3*7)+(2*1)+(1*8)=114
114 % 10 = 4
So 162147-18-4 is a valid CAS Registry Number.

, p. 2045 - 2058 (2007/10/03)
The biomimetic first total synthesis of michellamines A, B, and C (1a-c), naturally occurring quateraryl alkaloids with high anti-HIV activity, is described. Key precursors are the molecular "halves" of michellamines, the antimalarial naphthylisoquinoline
