Check Digit Verification of cas no

The CAS Registry Mumber 1333261-97-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,3,3,2,6 and 1 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1333261-97:
(9*1)+(8*3)+(7*3)+(6*3)+(5*2)+(4*6)+(3*1)+(2*9)+(1*7)=134
134 % 10 = 4
So 1333261-97-4 is a valid CAS Registry Number.

Rhenium complex-catalyzed acylative cleavage of ethers with acyl chlorides

Umeda, Rui,Nishimura, Takashi,Kaiba, Kenta,Tanaka, Toshimasa,Takahashi, Yuuki,Nishiyama, Yutaka

experimental part, p. 7217 - 7221 (2011/10/08)

It was found that rhenium complex was an efficient catalyst for the acylative cleavage of C-O bond of ethers with acyl chlorides. When acyclic ethers were allowed to react with acyl chlorides in the presence of a catalytic amount of ReBr(CO)5, acylative cleavage of C-O bond of acyclic ethers smoothly proceeded to give the corresponding esters in moderate to good yields. Similarly, cyclic ethers were acylative cleaved by acyl chlorides to give the corresponding chloro substituted esters in good yields by the use of Re 2O7 catalyst.
