Check Digit Verification of cas no

The CAS Registry Mumber 1346260-42-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,4,6,2,6 and 0 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1346260-42:
(9*1)+(8*3)+(7*4)+(6*6)+(5*2)+(4*6)+(3*0)+(2*4)+(1*2)=141
141 % 10 = 1
So 1346260-42-1 is a valid CAS Registry Number.

Synthesis of 1,2-diketones from β-keto nitriles via a protection-oxidative-decyanation-deprotection protocol

Liu, Yu,Yun, Xiliu,Zhang-Negrerie, Daisy,Huang, Jianhui,Du, Yunfei,Zhao, Kang

, p. 2984 - 2994 (2011/11/04)

A variety of 1,2-diketones were prepared from -keto nitriles via a three-step protocol including the protection of the ketones with methoxyamine, oxidative decyanation, and microwave-assisted deprotection in the final step. This approach provides a novel and efficient access to a wide scope of symmetric and unsymmetric 1,2-diketones using molecular oxygen as the oxidant in the decyanation process.
