Check Digit Verification of cas no

The CAS Registry Mumber 156147-56-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,6,1,4 and 7 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 156147-56:
(8*1)+(7*5)+(6*6)+(5*1)+(4*4)+(3*7)+(2*5)+(1*6)=137
137 % 10 = 7
So 156147-56-7 is a valid CAS Registry Number.

A new high yield preparation of benzyl phenethyl ethers by phase transfer catalysis

Lopez-Calahorra, Francisco,Ballart, Berta,Hombrados, Felix,Marti, Josep

, p. 795 - 799 (1998)

A phase transfer method to prepare benzyl phenethyl ethers from electron-rich benzyl halides and 2-phenylethanols supporting electron- withdrawing groups is described. The yields are excellent, in contrast to the very low ones previously reported for the same kind of compounds prepared by other ways.
