188569-20-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 188569-20-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,8,5,6 and 9 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 188569-20:
(8*1)+(7*8)+(6*8)+(5*5)+(4*6)+(3*9)+(2*2)+(1*0)=192
192 % 10 = 2
So 188569-20-2 is a valid CAS Registry Number.

Horikawa, Manabu,Nakajima, Terumi,Ohfune, Yasufumi
, p. 253 - 254 (2007/10/03)
Both enantiomers of α-benzyl and α-carboxymethyl serines (1, 2) were efficiently synthesized starting with the known phenyl acetol via an intramolecular asymmetric Strecker synthesis.
