81576-72-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 81576-72-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,5,7 and 6 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 81576-72:
(7*8)+(6*1)+(5*5)+(4*7)+(3*6)+(2*7)+(1*2)=149
149 % 10 = 9
So 81576-72-9 is a valid CAS Registry Number.

Synthesis of substituted cyclohexenyl-based β-amino acids by ring-closing metathesis
Abell, Andrew D.,Gardiner, James
, p. 3663 - 3666 (2002)
(equation presented) A versatile ring-closing metathesis (RCM) approach has been developed for the preparation of cis and trans cyclohexenyl-based β-amino acids that are either unsubstituted (3) or substituted (10 and 12) at the α-position.
