Check Digit Verification of cas no

The CAS Registry Mumber 208644-71-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,8,6,4 and 4 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 208644-71:
(8*2)+(7*0)+(6*8)+(5*6)+(4*4)+(3*4)+(2*7)+(1*1)=137
137 % 10 = 7
So 208644-71-7 is a valid CAS Registry Number.

Chemical synthesis of (4,6-Pyr)-Gal β1→4GlcNacβ1→3Fucβ1→OMe: A pyruvated trisaccharide related to the cell aggregation of the sponge Microciona prolifera

Deng, Shaojiang,Yu, Biao,Guo, Zhongwu,Hui, Yongzheng

, p. 439 - 452 (1998)

4,6-O-[(R)-1-carboxylethylidene] Galβ1→4GlcNAcβ1→3Fucβ1→OMe, a pyruvated trisaccharide unit involved in the aggregation factor of the marine sponge Microciona prolifera, was synthesized stereospecifically and unambiguously employing thioglycosides as glycosyl donors to construct glycosidic bonds.
