1239955-04-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1239955-04-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,3,9,9,5 and 5 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1239955-04:
(9*1)+(8*2)+(7*3)+(6*9)+(5*9)+(4*5)+(3*5)+(2*0)+(1*4)=184
184 % 10 = 4
So 1239955-04-4 is a valid CAS Registry Number.

Wang, Xuefeng,Andrews, Lester
, p. 9260 - 9265 (2009)
Thorium atoms react with NF3, PF3, and AsF 3 to produce the first actinide triplet state pnictinidene molecules, N÷ThF3, P÷ThF3, and As÷ThF 3, which are trapped in solid argon and identifie
