Check Digit Verification of cas no

The CAS Registry Mumber 102990-49-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,2,9,9 and 0 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 102990-49:
(8*1)+(7*0)+(6*2)+(5*9)+(4*9)+(3*0)+(2*4)+(1*9)=118
118 % 10 = 8
So 102990-49-8 is a valid CAS Registry Number.

Amines and ammonium compounds. CXCI. The Stevens rearrangement with the participation of the N,N-dimethylcarbamoylmethyl group

Kocharyan, S. T.,Voskanyan, V. S.,Razina, T. L.,Babayan, A. T.

, p. 1721 - 1724 (2007/10/02)

Under the influence of powdered potassium hydroxide in benzene ammonium salts containing a group of the allyl or propargyl type in addition to an N,N-dimethylcarbamoylmethyl group enter smoothly into a Stevens 3,2-rearrangement with the formation of the N,N-dimethylamides of 2-dimethylamino-4-pentenoic and 2-dimethylamino-3,4-pentadienoic acids respectively.The salt, which contains a benzyl group as migrating group, forms a mixture of products from the Stevens and Sommelet rearrangements.The possibility of rearrangement under the influence of sodium in DMSO was demonstrated.
