86977-80-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 86977-80-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,6,9,7 and 7 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 86977-80:
(7*8)+(6*6)+(5*9)+(4*7)+(3*7)+(2*8)+(1*0)=202
202 % 10 = 2
So 86977-80-2 is a valid CAS Registry Number.

Synthesis of Some Novel Polycyclic Mono- and Di-cis-β-lactams
Sharma, S. D.,Kaur, Sukhjinder,Mehra, Usha

1-Methylthio-3,4-dihydroisoquinoline (1) on annelation with aryloxyacetic acids (2) in the presence of POCl3/Et3N in CH2Cl2 affords β-methylthio-β-lactams (3, 4 and 5).Desulphurisation of 3 - 5 with Raney-Ni yields cis-β-lactams (6, 7 and 8) respectively.
