139391-04-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 139391-04-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,3,9 and 1 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 139391-04:
(8*1)+(7*3)+(6*9)+(5*3)+(4*9)+(3*1)+(2*0)+(1*4)=141
141 % 10 = 1
So 139391-04-1 is a valid CAS Registry Number.

A Novel Approach to α-Silylmethylene-β-lactams via Rh-catalyzed Silylcarbonylation of Propargylamine Derivatives
Matsuda, Isamu,Sakakibara, Jun,Nagashima, Hideo
, p. 7431 - 7434 (2007/10/02)
α-Silylmethylene-β-lactams are successfully constructed by the one-pot coupling of a substituted propargylamine derivative, a triorganosilane, and CO with the catalysis of Rh4(CO)12 and DBU.
