Check Digit Verification of cas no

The CAS Registry Mumber 111233-40-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,1,2,3 and 3 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 111233-40:
(8*1)+(7*1)+(6*1)+(5*2)+(4*3)+(3*3)+(2*4)+(1*0)=60
60 % 10 = 0
So 111233-40-0 is a valid CAS Registry Number.

Scavenging byproducts in the sulfoxide glycosylation reaction: Application to the synthesis of ciclamycin 0

Gildersleeve, Jeff,Smith, Andri,Sakurai, Kaori,Raghavan, Subharekha,Kahne, Daniel

, p. 6176 - 6182 (2007/10/03)

We have developed a direct and efficient route for the synthesis of ciclamycin 0 using the sulfoxide glycosylation reaction to form the glycosidic linkages. In the course of completing the synthesis of ciclamycin 0, we developed new glycosylation conditions that improve the outcome of the sulfoxide reaction. The conditions involve the addition of agents that scavenge phenylsulfenyl triflate, a highly reactive byproduct that forms following activation of anomeric sulfoxides with triflic anhydride.
