1104079-21-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1104079-21-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,0,4,0,7 and 9 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1104079-21:
(9*1)+(8*1)+(7*0)+(6*4)+(5*0)+(4*7)+(3*9)+(2*2)+(1*1)=101
101 % 10 = 1
So 1104079-21-1 is a valid CAS Registry Number.

scheme or table, p. 45 - 47 (2009/04/11)
In the presence of RhH(PPh3)4, the reaction of 1,2-alkadienes, tetramethyldiphosphine disulfide, and camphorsulfonic acid gave (E)-2-dimethylthiophosphinoyl-2-alkenes. The reaction involved the P-P cleavage and the transfer of the th
