Check Digit Verification of cas no

The CAS Registry Mumber 1249139-69-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,4,9,1,3 and 9 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1249139-69:
(9*1)+(8*2)+(7*4)+(6*9)+(5*1)+(4*3)+(3*9)+(2*6)+(1*9)=172
172 % 10 = 2
So 1249139-69-2 is a valid CAS Registry Number.

Highly efficient three-component Strecker-type reaction catalyzed by MgI2 etherate under solvent-free conditions

Li, Pengcheng,Zhang, Yongdong,Chen, Zhili,Zhang, Xingxian

, p. 1854 - 1858 (2017)

A concise, straightforward and efficient method has been developed for the synthesis of α-aminonitriles by an one-pot three-component condensation of aldehydes or ketones, amines and trimethylsilyl cyanide catalyzed by MgI2 etherate under solvent-free conditions. This protocol has some advantages such as mild reaction condition, simple work-up, short reaction time and high product yields.

MgI2 etherate-catalysed Strecker reaction: A facile and efficient synthesis of α-aminonitriles from aldimines and trimethylsilyl cyanide

Lu, Yongping,Wang, Yanping,Zhang, Xingxian

, p. 709 - 711 (2014/01/17)

A mild and efficient procedure for the synthesis of a-aminonitriles is achieved by treatment of aldimines with trimethylsilyl cyanide catalysed by MgI2 etherate.
