155620-77-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 155620-77-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,5,6,2 and 0 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 155620-77:
(8*1)+(7*5)+(6*5)+(5*6)+(4*2)+(3*0)+(2*7)+(1*7)=132
132 % 10 = 2
So 155620-77-2 is a valid CAS Registry Number.

Enamines from formamides. Synthesis of 1,2,3,4-tetrahydro-1-substituted β-carbolines
Vohra,Maclean
, p. 1660 - 1667 (2007/10/02)
Pyridines and benzopyridines substituted with trimethylsilylmethyl groups, α or γ to the nitrogen atom, have been found to react with formamides by way of a Peterson reaction to form enamines. Trimethylsilylmethylbenzene behaved similarly. The enamines pr
