215313-77-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 215313-77-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,5,3,1 and 3 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 215313-77:
(8*2)+(7*1)+(6*5)+(5*3)+(4*1)+(3*3)+(2*7)+(1*7)=102
102 % 10 = 2
So 215313-77-2 is a valid CAS Registry Number.

Push-pull quinoidal porphyrins
Smith, Martin J.,Blake, Iain M.,Clegg, William,Anderson, Harry L.
, p. 3648 - 3654 (2018)
A family of push-pull quinoidal porphyrin monomers has been prepared from a meso-formyl porphyrin by bromination, thioacetal formation, palladium-catalyzed coupling with malononitrile and oxidation with DDQ. Attempts at extending this synthesis to a push-
