Check Digit Verification of cas no

The CAS Registry Mumber 1440963-42-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,4,0,9,6 and 3 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1440963-42:
(9*1)+(8*4)+(7*4)+(6*0)+(5*9)+(4*6)+(3*3)+(2*4)+(1*2)=157
157 % 10 = 7
So 1440963-42-7 is a valid CAS Registry Number.

Aniline mediated oxidative C-C bond cleavage of α-alkoxy aldehydes in air and a model reaction for the synthesis of α-(d)-amino acid derivatives

Hu, Bin,Li, Yunfeng,Li, Zhongjun,Meng, Xiangbao

, p. 4138 - 4141 (2013/07/05)

A metal-free and 4-methyl aniline mediated method for the oxidative C-C bond cleavage has been developed. The reaction proceeds in air using molecular oxygen as the oxidant, affording one-carbon shortened esters in moderate to good yields within a short time. Moreover, it provides a model reaction for the highly enantioselective synthesis of (d)-serine esters by combining with a l-proline catalyzed Mannich reaction.
