Check Digit Verification of cas no

The CAS Registry Mumber 154072-97-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,4,0,7 and 2 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 154072-97:
(8*1)+(7*5)+(6*4)+(5*0)+(4*7)+(3*2)+(2*9)+(1*7)=126
126 % 10 = 6
So 154072-97-6 is a valid CAS Registry Number.

New access to carbonyl ylides by the silicon-based 1,3-elimination and their [3 + 2] cycloadditions to activated alkenes and alkynes: One-step synthesis of dihydrofurans and tetrahydrofurans

Hojo, Makoto,Ohkuma, Masakazu,Ishibashi, Naruyasu,Hosomi, Akira

, p. 5943 - 5946 (1993)

Simple aryl-substituted carbonyl ylides are generated by the silicon-based 1,3-elimination of chloromethyl trimethylsilyl(α-aryl)methyl ethers promoted by flouride ion under mild and neutral conditions which provide an one-step synthesis of dihydrofurans
