Check Digit Verification of cas no

The CAS Registry Mumber 50256-33-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,0,2,5 and 6 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 50256-33:
(7*5)+(6*0)+(5*2)+(4*5)+(3*6)+(2*3)+(1*3)=92
92 % 10 = 2
So 50256-33-2 is a valid CAS Registry Number.

Identification of 3,6-di-O-acetyl-1,2,4-O-orthoacetyl-α-d- glucopyranose as a direct evidence for the 4-O-acyl group participation in glycosylation

Ma, Yuyong,Lian, Gaoyan,Li, Yao,Yu, Biao

supporting information; experimental part, p. 7515 - 7517 (2011/09/13)

The formation of 3,6-di-O-acetyl-1,2,4-O-orthoacetyl-α-d- glucopyranose was observed in the gold(i)-catalyzed glycosidation of peracetyl glucopyranosyl ortho-hexynylbenzoate; experiments with substrates bearing deuterium labeled 2-O-acetyl or 4-O-acetyl groups indicated that the orthoacetate was derived from the 4-O-acetyl group, which provided a direct evidence for the remote participation of the 4-O-acyl group in glycosylation.
