Check Digit Verification of cas no

The CAS Registry Mumber 17547-64-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,7,5,4 and 7 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 17547-64:
(7*1)+(6*7)+(5*5)+(4*4)+(3*7)+(2*6)+(1*4)=127
127 % 10 = 7
So 17547-64-7 is a valid CAS Registry Number.

Nucleophilic Displacement with Heterocycles as Leaving Groups. Part 16. Reactions of Secondary Alkyl Primary Amines with 5,6,8,9-Tetrahydro-7-phenyldibenzoxanthylium Trifluoromethanesulphonate to give Intermediates Solvolysing without Rearrangement

Katritzky, Alan R.,Lopez-Rodriguez, Maria L.,Keay, James G.,King, Roy W.

, p. 165 - 170 (2007/10/02)

Representative secondary alkyl primary amines R1R2CHNH2 react with the title pyrylium cation in acetic acid, alcohols, phenols, and NN-dimethylaniline acting as nucleophilic solvents to give O- and C-(secondary alkyl) products.Absence of carbenium ion rearrangements is consistent with reaction via intimate ion-molecule pairs formed rapidly from the corresponding pyridinium cations.
