129801-40-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 129801-40-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,8,0 and 1 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 129801-40:
(8*1)+(7*2)+(6*9)+(5*8)+(4*0)+(3*1)+(2*4)+(1*0)=127
127 % 10 = 7
So 129801-40-7 is a valid CAS Registry Number.

, p. 1727 - 1731 (2007/10/02)
Reaction of the iminophosphoranes (7)-(9), derived from α-azidocinnamates and triphenylphosphine, with aromatic isocyanates gives either 1-arylaminoisoquinoline-3-carboxylates (10)-(12) or the corresponding carbodi-imides (14)-(18) which by thermal treatm
