849683-31-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 849683-31-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,4,9,6,8 and 3 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 849683-31:
(8*8)+(7*4)+(6*9)+(5*6)+(4*8)+(3*3)+(2*3)+(1*1)=224
224 % 10 = 4
So 849683-31-4 is a valid CAS Registry Number.

Selective extraction of higher fullerenes using cyclic dimers of zinc porphyrins
Shoji, Yoshiaki,Tashiro, Kentaro,Aida, Takuzo
, p. 6570 - 6571 (2007/10/03)
Higher fullerenes (≥C76) were selectively extracted from a fullerene mixture obtained from a combustion-based industrial production source by cyclic dimers of β-unsubstituted porphyrin zinc complexes 2C5-2C7 with C5-C7 alk
