Check Digit Verification of cas no

The CAS Registry Mumber 1235475-84-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,3,5,4,7 and 5 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1235475-84:
(9*1)+(8*2)+(7*3)+(6*5)+(5*4)+(4*7)+(3*5)+(2*8)+(1*4)=159
159 % 10 = 9
So 1235475-84-9 is a valid CAS Registry Number.

Resolution of N-Protected amino alcohols by porcine pancreatic lipase

Magrioti, Victoria,Fotakopoulou, Irene,Athinaios, Nicolaos,Anastasopoulou, Panoula,Constantinou-Kokotou, Violetta,Kokotos, George

, p. 159 - 162 (2010)

The resolution of 2-amino alcohols protected by urethane-type groups either via porcine pancreatic lipase (PPL) hydrolysis of the corresponding racemic acetates or via PPL catalyzed transesterification of racemic alcohols was studied. In both cases, Boc protecting group led to better chemical yields and enantiopurities than Z and Fmoc protecting groups. Furthermore, a simple and efficient method for the synthesis of the medicinally interesting optically pure (R)-2- aminohexadecanol was developed.
