1198428-88-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1198428-88-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,9,8,4,2 and 8 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1198428-88:
(9*1)+(8*1)+(7*9)+(6*8)+(5*4)+(4*2)+(3*8)+(2*8)+(1*8)=204
204 % 10 = 4
So 1198428-88-4 is a valid CAS Registry Number.

Pd(OAc)2-catalyzed decomposition of ethyl 2-diazo-4-(4-indolyl)-3- oxobutanoate leads to a tricyclic tetrahydrobenzindole compound formed by a formal C-H insertion reaction. This tricyclic indole rearranges to a novel and thermodynamically more stable nap
