1403981-55-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1403981-55-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,0,3,9,8 and 1 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1403981-55:
(9*1)+(8*4)+(7*0)+(6*3)+(5*9)+(4*8)+(3*1)+(2*5)+(1*5)=154
154 % 10 = 4
So 1403981-55-4 is a valid CAS Registry Number.

Platinum-catalyzed oxoarylations of ynamides with nitrones
Bhunia, Sabyasachi,Chang, Chin-Jung,Liu, Rai-Shung
, p. 5522 - 5525,4 (2012)
A new platinum-catalyzed oxoarylation of ynamides with nitrones is reported. Cascade sequences for the synthesis of indolin-2-ones via NaBH 3CN reduction in situ of the initially formed oxoarylation products are also developed.
