Check Digit Verification of cas no

The CAS Registry Mumber 196959-49-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,6,9,5 and 9 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 196959-49:
(8*1)+(7*9)+(6*6)+(5*9)+(4*5)+(3*9)+(2*4)+(1*9)=216
216 % 10 = 6
So 196959-49-6 is a valid CAS Registry Number.

METHOD OF SYNTHESIZING LEVOROTATORY P-HYDROXYPHENYLGLYCINE COMPOUNDS

-

Paragraph 0097-0100, (2014/12/09)

The present invention relates to the field of chemical synthesis, particularly to a method of synthesizing levorotatory p-hydroxyphenylglycine compounds, which eliminates the subsequent processes of resolution, racemization processings, etc., simplifies o

The catalytic synthesis of carboniolamide: The role of sp 3 hybridized oxygen

Zhang, Yi,Dai, Yuchi,Li, Guigen,Cheng, Xu

supporting information, (2015/08/06)

A catalytic synthesis of carboniolamide has been reported. The strategy was straightforward with aldehyde and amide as starting materials. The products can be isolated as precipitates from the reaction mixture. The factor that stabilizes the labile functionality of hemiaminal was elucidated as a sp 3 hybridized oxygen.
