1335231-69-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1335231-69-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,3,5,2,3 and 1 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1335231-69:
(9*1)+(8*3)+(7*3)+(6*5)+(5*2)+(4*3)+(3*1)+(2*6)+(1*9)=130
130 % 10 = 0
So 1335231-69-0 is a valid CAS Registry Number.

Novel synthesis of pseudopeptides bearing a difluoromethyl group by Ugi reactionand desulfanylation
Wu, Jingjing,Li, Hui,Cao, Song
, p. 1070 - 1074 (2011/10/04)
Thirteen difluoromethyl-containing pseudopeptides were synthesized by Ugi reaction using the novel building block 2,2-difluoro-2- (phenylthio)acetic acid (2) as one component, followed by removal of the phenylsulfanyl protecting group in the presence of t
