128316-43-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 128316-43-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,3,1 and 6 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 128316-43:
(8*1)+(7*2)+(6*8)+(5*3)+(4*1)+(3*6)+(2*4)+(1*3)=118
118 % 10 = 8
So 128316-43-8 is a valid CAS Registry Number.

Palladium-catalysed polycyclisation-anion capture processes
Grigg,Dorrity,Malone,Sridharan,Sukirthalingam
, p. 1343 - 1346 (2007/10/02)
Aryl iodides containing appropriately located 1, n-diene, -diyne, and -enyne moieties undergo palladium catalysed bis-cyclisation with anion capture (H-, Ph-) apart from the 1, n-enyne which undergoes a tri-cyclisation without anion
