137654-34-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 137654-34-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,7,6,5 and 4 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 137654-34:
(8*1)+(7*3)+(6*7)+(5*6)+(4*5)+(3*4)+(2*3)+(1*4)=143
143 % 10 = 3
So 137654-34-3 is a valid CAS Registry Number.

, p. 7429 - 7436 (2007/10/02)
Synthesis of 1H-4,4a,5,9b-tetrahydroindeno[1,2-b]pyridines has been accomplished by catalytic hydrogenation of 4H-4a,5-dihydroindenopyridines. The isomerization of 1H-4,4a,5,9b-tetrahydroindenopyridines containing an acyl function at C-3 leads to 3H-4,4a,
