Check Digit Verification of cas no

The CAS Registry Mumber 1767-71-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,7,6 and 7 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1767-71:
(6*1)+(5*7)+(4*6)+(3*7)+(2*7)+(1*1)=101
101 % 10 = 1
So 1767-71-1 is a valid CAS Registry Number.

I2O5/DBU mediated direct α-phosphoryloxylation of ketones with H-phosphonates leading to α-hydroxyketone phosphates

Liu, Chunli,Wei, Wei,Yang, Daoshan,Zheng, Yuanyuan,Bi, Yanshuai,Chen, Min,Wang, Hua

, p. 6901 - 6906 (2015)

A simple and convenient procedure has been developed for the construction of α-hydroxyketone phosphates via I2O5/DBU mediated direct α-phosphoryloxylation of ketones with H-phosphonates. This new reaction proceeds through three steps involving α-iodination of ketones, oxidation of H-phosphonates, and nucleophilic substitution of α-iodo ketones to access a series of α-hydroxyketone phosphates of biological importance.
