67041-43-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 67041-43-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,7,0,4 and 1 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 67041-43:
(7*6)+(6*7)+(5*0)+(4*4)+(3*1)+(2*4)+(1*3)=114
114 % 10 = 4
So 67041-43-4 is a valid CAS Registry Number.

O-sulfinylation with methanesulfonyl cyanide or p-toluenesulfonyl cyanide and DBU
Barton,Jaszberenyi,Theodorakis
, p. 2585 - 2588 (2007/10/02)
Reaction of methanesulfonyl cyanide or p-toluenesulfonyl cyanide with alcohols in the presence of 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU) gives sulfinates in good yield. A mechanistic scheme involving sulfinyl cyanates is suggested.
