29977-00-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 29977-00-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,9,9,7 and 7 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 29977-00:
(7*2)+(6*9)+(5*9)+(4*7)+(3*7)+(2*0)+(1*0)=162
162 % 10 = 2
So 29977-00-2 is a valid CAS Registry Number.

A new synthetic route to 3,4-bridged 1,6,6aλ4-trithiapentalenes
Zhang,Henry
, p. 1129 - 1130 (2001)
A new synthetic route to 3,4-bridged 1,6,6aλ4-trithiapentalenes is developed based on reactions of cyclic ketones with Bredereck's reagent followed by thiolation of keto dienamines with phosphorus pentasulfide or Lawesson's reagent.
