63987-70-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 63987-70-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,3,9,8 and 7 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 63987-70:
(7*6)+(6*3)+(5*9)+(4*8)+(3*7)+(2*7)+(1*0)=172
172 % 10 = 2
So 63987-70-2 is a valid CAS Registry Number.

, p. 1114 - 1119 (2008)
The Candida antarctica lipase A-catalysed N-acylation of ethyl 3-amino-2-ethylpropanoate rac-3 and methyl 3-amino-2-isopropylpropanoate rac-6 was performed with ethyl butanoate in tert-amyl alcohol at 4 °C. The resulting enantiomerically enriched derivati
