1174640-63-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1174640-63-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,7,4,6,4 and 0 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1174640-63:
(9*1)+(8*1)+(7*7)+(6*4)+(5*6)+(4*4)+(3*0)+(2*6)+(1*3)=151
151 % 10 = 1
So 1174640-63-1 is a valid CAS Registry Number.

DBU-catalyzed addition reactions of sulfonylimidates
Matsubara, Ryosuke,Kobayashi, Shu
, p. 3009 - 3011 (2008)
Sulfonylimidates react with various types of N-protected imines in the presence of a catalytic amount of DBU to afford β-aminosulfonylimidates in high yields and high anti-selectivities. The experimental procedure is described in detail. Georg Thieme Verlag Stuttgart.
