Check Digit Verification of cas no
The CAS Registry Mumber 52918-59-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,2,9,1 and 8 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 52918-59:
(7*5)+(6*2)+(5*9)+(4*1)+(3*8)+(2*5)+(1*9)=139
139 % 10 = 9
So 52918-59-9 is a valid CAS Registry Number.

The central six-C-atom chain of the title compound, C52H50O10, adopts a nearly planar extended conformation free from C//C, C//O and O//O 1,3-parallel interactions. The three torsion angles formed by these atoms have values of 177.4(2), 174.2(2) and -178.0(2)°. The bulky triphenylmethyl groups, which are oriented gauche to their neighboring acetoxy groups with O-C-C-O torsion angles of -69.8 (2) and -63.0 (2)°, cause no distortion of the bond lengths and bond angles of the sugar moiety.
