Check Digit Verification of cas no

The CAS Registry Mumber 100910-72-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,0,9,1 and 0 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 100910-72:
(8*1)+(7*0)+(6*0)+(5*9)+(4*1)+(3*0)+(2*7)+(1*2)=73
73 % 10 = 3
So 100910-72-3 is a valid CAS Registry Number.

Nucleophilic reaction of glycidol tosylate and the corresponding cyclic sulfate with various nucleophiles: A comparative study

Lohray,Rajesh,Bhushan

, p. 586 - 592 (2007/10/03)

The nucleophilic reaction of glycidol tosylate and the corresponding cyclic sulfate tosylate have been carried out with a number of nucleophiles to study the possible attack of nucleophiles at C1, C2 or C3 positions. The regioselectivity and reactivity of both the substrates i.e. epoxide tosylate 1 and the corresponding cyclic sulfate 2 have been compared and established that under similar conditions cyclic sulfate counterpart shows better regioselectivity and better reactivity than the corresponding epoxide.
