Check Digit Verification of cas no

The CAS Registry Mumber 87709-37-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,7,7,0 and 9 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 87709-37:
(7*8)+(6*7)+(5*7)+(4*0)+(3*9)+(2*3)+(1*7)=173
173 % 10 = 3
So 87709-37-3 is a valid CAS Registry Number.

One-pot synthesis of diaryliodonium salts using toluenesulfonic acid: A fast entry to electron-rich diaryliodonium tosylates and triflates

Zhu, Mingzhao,Jalalian, Nazli,Olofsson, Berit

, p. 592 - 596 (2008)

A direct synthesis of symmetric and unsymmetric electron-rich diaryliodonium salts is described. The use of MCPBA and toluenesulfonic acid delivers diaryliodonium tosylates in high yields. An in situ anion exchange has also been developed, giving access to the corresponding triflate salts. Georg Thieme Verlag Stuttgart.
