Check Digit Verification of cas no

The CAS Registry Mumber 256229-07-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,6,2,2 and 9 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 256229-07:
(8*2)+(7*5)+(6*6)+(5*2)+(4*2)+(3*9)+(2*0)+(1*7)=139
139 % 10 = 9
So 256229-07-9 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

supporting information, 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.
