93217-58-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 93217-58-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,3,2,1 and 7 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 93217-58:
(7*9)+(6*3)+(5*2)+(4*1)+(3*7)+(2*5)+(1*8)=134
134 % 10 = 4
So 93217-58-4 is a valid CAS Registry Number.

Fused Heterocycles from Pyrrolethiols
Harris, Roger L. N.,McFadden, Helen G.
, p. 1473 - 1481 (2007/10/02)
Pyrrolethiols are highly reactive bidentate nucleophiles which give a wide variety of fused heterocyclic ring systems on reaction with acylating and alkylating agents via S-substituted intermediates that are in most instances themselves isolable.Represent
