181948-09-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 181948-09-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,1,9,4 and 8 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 181948-09:
(8*1)+(7*8)+(6*1)+(5*9)+(4*4)+(3*8)+(2*0)+(1*9)=164
164 % 10 = 4
So 181948-09-4 is a valid CAS Registry Number.

Enzymatic resolution of amines and amino alcohols using pent-4-enoyl derivatives
Takayama, Shuichi,Moree, Wilna J.,Wong, Chi-Huey
, p. 6287 - 6290 (1996)
Racemic amines and amino alcohols were enzymatically resolved by enantioselective acylation using cyanomethyl pent-4-enoate or by enantioselective enzymatic hydrolysis of the dipent-4-enoyl derivatives of amino alcohols to afford chiral pent-4-enamides wh
