Check Digit Verification of cas no

The CAS Registry Mumber 681280-01-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,8,1,2,8 and 0 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 681280-01:
(8*6)+(7*8)+(6*1)+(5*2)+(4*8)+(3*0)+(2*0)+(1*1)=153
153 % 10 = 3
So 681280-01-3 is a valid CAS Registry Number.

A tetra-: N -butylammonium iodide mediated reaction of indoles with Bunte salts: Efficient 3-sulfenylation of indoles under metal-free and oxidant-free conditions

Li, Jian,Cai, Zhong-Jian,Wang, Shun-Yi,Ji, Shun-Jun

supporting information, p. 9384 - 9387 (2016/10/13)

A highly efficient tetra-n-butylammonium iodide (TBAI) triggered procedure for 3-sulfenylation of indoles with Bunte salts is demonstrated. This protocol provides a simple strategy to prepare 3-alkylthioindoles and 3-arylthioindoles from the corresponding indoles under metal-free and oxidant-free conditions.
