136538-91-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 136538-91-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,6,5,3 and 8 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 136538-91:
(8*1)+(7*3)+(6*6)+(5*5)+(4*3)+(3*8)+(2*9)+(1*1)=145
145 % 10 = 5
So 136538-91-5 is a valid CAS Registry Number.

Gilow, Helmuth M.,Brown, Christopher S.,Copeland, John N.,Kelly, Keith E.
, p. 1025 - 1034 (2007/10/02)
Methylsulfenylation of 1-substituted pyrroles and indoles was observed using 1-(methylthio)morpholine and an acid catalyst or with methylsulfenyl chloride and excess pyridine. 1-Substituents which are activating or weakly deactivating towards electrophili
