Check Digit Verification of cas no

The CAS Registry Mumber 124706-40-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,4,7,0 and 6 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 124706-40:
(8*1)+(7*2)+(6*4)+(5*7)+(4*0)+(3*6)+(2*4)+(1*0)=107
107 % 10 = 7
So 124706-40-7 is a valid CAS Registry Number.

supporting information; experimental part, p. 2132 - 2140 (2010/04/26)

The reaction of N-(3-phenylpropionyloxy)phthalimide (1a) and N-tosyloxy (5a,b) derivatives with nucleophiles was examined and found to give the products via Lossen-type rearrangement. In order to obtain the scope of this reaction mechanism, further studies the reaction of several N-sulfonyloxyimide derivatives with various nucleophiles under similar conditions were carried out and found to afford the corresponding same types of products in high yields.
