51708-15-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 51708-15-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,1,7,0 and 8 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 51708-15:
(7*5)+(6*1)+(5*7)+(4*0)+(3*8)+(2*1)+(1*5)=107
107 % 10 = 7
So 51708-15-7 is a valid CAS Registry Number.

Synthesis of 7,8,9,10-tetrahydropyrido[3',4':4,5]pyrrolo[2,3-c]quinolines
Schonafinger,Yasenchak,Vollman,Ong
, p. 535 - 537 (1988)
A series of structurally novel 7,8,9,10-tetrahydropyrido [3',4':4,5]pyrrolo[2,3-c]quinolines, 4a-c, were synthesized via a facile Fischer indole cyclization from the appropriately substituted hydrazinoquinolines 2a-c. Acetamides 4a,c were hydrolyzed to 5a
