444709-91-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 444709-91-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,4,4,7,0 and 9 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 444709-91:
(8*4)+(7*4)+(6*4)+(5*7)+(4*0)+(3*9)+(2*9)+(1*1)=165
165 % 10 = 5
So 444709-91-5 is a valid CAS Registry Number.

Efficient and practical syntheses of mannose tri-, tetra-, penta-, hexa-, hepta-, and octasaccharides existing in N-glycans
Zhang, Jianjun,Kong, Fanzuo
, p. 243 - 252 (2007/10/03)
An efficient and practical regio- and stereoselective synthesis of mannose tri-, tetra-, penta-, hexa-, hepta-, and octasaccharides of N-glycans was achieved using simple mannosyl derivatives as the starting materials.
