Check Digit Verification of cas no
The CAS Registry Mumber 152035-56-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,2,0,3 and 5 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 152035-56:
(8*1)+(7*5)+(6*2)+(5*0)+(4*3)+(3*5)+(2*5)+(1*6)=98
98 % 10 = 8
So 152035-56-8 is a valid CAS Registry Number.

Ma, Wuping,Slebodnick, Carla,Ibers, James A.
, p. 6349 - 6353 (2007/10/02)
The synthesis and characterization of three new five-atom-linked "capped" porphyrins, 6, 12, and 18, are reported.The general synthetic procedure involves synthesis of a tetraaldehyde "cap" by reacting the five-atom "arm" with 1,2,4,5-tetrahydroxybenzene
