Check Digit Verification of cas no

The CAS Registry Mumber 1393083-69-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,9,3,0,8 and 3 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1393083-69:
(9*1)+(8*3)+(7*9)+(6*3)+(5*0)+(4*8)+(3*3)+(2*6)+(1*9)=176
176 % 10 = 6
So 1393083-69-6 is a valid CAS Registry Number.

A facile and highly stereoselective synthesis of 1-thiotrehalose

Xin, Guohong,Zhu, Xiangming

supporting information; experimental part, p. 4309 - 4312 (2012/09/22)

A facile and highly stereoselective synthesis of 1-thiotrehalose, that is, α,α-S-linked trehalose, is described. Glycosylation of configurationally pure α-glucosyl thiol 5 with glucosyl trichloroacetimidate 6 or glucosyl thioimidate 9 followed by deprotection afforded 1-thiotrehalose in excellent α-stereoselectivity and high yield. A different synthetic route to the key building block, α-glucosyl thiol 5, was also investigated in this report.
