1391157-54-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1391157-54-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,9,1,1,5 and 7 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1391157-54:
(9*1)+(8*3)+(7*9)+(6*1)+(5*1)+(4*5)+(3*7)+(2*5)+(1*4)=162
162 % 10 = 2
So 1391157-54-2 is a valid CAS Registry Number.

Iron-catalyzed unexpected easy access to stereodefined trimethylsilyl vinyl ketenes
Chai, Guobi,Fu, Chunling,Ma, Shengming
, p. 4058 - 4061 (2012/10/08)
Stereodefined trimethylsilyl vinyl ketenes with polysubstitution have been synthesized highly regio- and stereoselectively via an iron-catalyzed reaction of 2-trimethylsilyl-2,3-allenoates with Grignard reagents in good to excellent yields. The reaction w
