Check Digit Verification of cas no

The CAS Registry Mumber 21994-90-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,9,9 and 4 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 21994-90:
(7*2)+(6*1)+(5*9)+(4*9)+(3*4)+(2*9)+(1*0)=131
131 % 10 = 1
So 21994-90-1 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.
