Check Digit Verification of cas no

The CAS Registry Mumber 1250346-26-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,0,3,4 and 6 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1250346-26:
(9*1)+(8*2)+(7*5)+(6*0)+(5*3)+(4*4)+(3*6)+(2*2)+(1*6)=119
119 % 10 = 9
So 1250346-26-9 is a valid CAS Registry Number.

Versatile set of orthogonal protecting groups for the preparation of highly branched oligosaccharides

Boltje, Thomas J.,Li, Chunxia,Boons, Geert-Jan

supporting information; experimental part, p. 4636 - 4639 (2010/12/19)

A new set of orthogonal protecting groups has been developed based on the use of a diethylisopropylsilyl (DEIPS), methylnaphthyl (Nap), allyl ether, and levulinoyl (Lev) ester. The protecting groups are ideally suited for the preparation of highly branche
