676335-59-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 676335-59-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,7,6,3,3 and 5 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 676335-59:
(8*6)+(7*7)+(6*6)+(5*3)+(4*3)+(3*5)+(2*5)+(1*9)=194
194 % 10 = 4
So 676335-59-4 is a valid CAS Registry Number.

Concise total synthesis of (+)-carpamic acid
Randl, Stefan,Blechert, Siegfried
, p. 1167 - 1169 (2007/10/03)
We report herein an efficient enantioselective synthesis of (+)-carpamic acid, with nine steps as the longest linear sequence, the key strategy being based on a novel sequence of a cross-metathesis (CM) reaction and a subsequent cyclizing reductive amination to form the piperidine ring.
