136706-12-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 136706-12-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,6,7,0 and 6 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 136706-12:
(8*1)+(7*3)+(6*6)+(5*7)+(4*0)+(3*6)+(2*1)+(1*2)=122
122 % 10 = 2
So 136706-12-2 is a valid CAS Registry Number.

Marx, Thomas,Breitmaier, Eberhard
, p. 183 - 186 (2007/10/02)
Chiral porphyrins 9 and 10 with C-connected (-)-menthyl residues are prepared starting from (-)-menthol 1 in eight steps, finally involving cyclization of 3-formyl-β-(p-menth-3-yl)styrene (6) with pyrrole (7) or the 2,2'-dipyrrylmethane 8. Key Words: Porp
