219906-49-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 219906-49-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,9,9,0 and 6 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 219906-49:
(8*2)+(7*1)+(6*9)+(5*9)+(4*0)+(3*6)+(2*4)+(1*9)=157
157 % 10 = 7
So 219906-49-7 is a valid CAS Registry Number.

, p. 4091 - 4102 (2016)

A series of novel OSW-1 analogues were synthesized by coupling disaccharides (2-O-4-methoxylbenzoyl-β-D-xylopyranosyl-(1→3)-2-O-acetyl-α-L-arabinopyranosyl) or (2-O-4-(E)-cinnamoyl-β-D-xylopyranosyl-(1→3)-2-O-acetyl-α-L-arabinopyranosyl) and their 1→4 lin
