128797-70-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 128797-70-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,7,9 and 7 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 128797-70:
(8*1)+(7*2)+(6*8)+(5*7)+(4*9)+(3*7)+(2*7)+(1*0)=176
176 % 10 = 6
So 128797-70-6 is a valid CAS Registry Number.

Synthesis of Thiocarbonyl and Heterocyclic Compounds from 2-Methylene-1,3-dithietanes
Okajima, Nobuyuki,Okada, Yoshiyuki
, p. 567 - 574 (2007/10/02)
2-Methyl-1,3-dithietanes bearing electron withdrawing groups on the methylene carbon atom were synthesized and their reactivities were studied.These compounds readily underwent a ring-opening reaction with a variety of nucleophilic reagents such as amines
