911654-73-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 911654-73-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,1,1,6,5 and 4 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 911654-73:
(8*9)+(7*1)+(6*1)+(5*6)+(4*5)+(3*4)+(2*7)+(1*3)=164
164 % 10 = 4
So 911654-73-4 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.
