CAS DataBase Reference: 4-(4-Hydroxyphenyl)-1(2H)-phthalazinone polymer with bis(4-fluorophenyl)methanone and 1,1'-sulfonylbis[4-chlorobenzene](CAS DataBase Reference)
NIST Chemistry Reference: 4-(4-Hydroxyphenyl)-1(2H)-phthalazinone polymer with bis(4-fluorophenyl)methanone and 1,1'-sulfonylbis[4-chlorobenzene](172402-80-1)
EPA Substance Registry System: 4-(4-Hydroxyphenyl)-1(2H)-phthalazinone polymer with bis(4-fluorophenyl)methanone and 1,1'-sulfonylbis[4-chlorobenzene](172402-80-1)
The CAS Registry Mumber 172402-80-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,2,4,0 and 2 respectively; the second part has 2 digits, 8 and 0 respectively. Calculate Digit Verification of CAS Registry Number 172402-80: (8*1)+(7*7)+(6*2)+(5*4)+(4*0)+(3*2)+(2*8)+(1*0)=111 111 % 10 = 1 So 172402-80-1 is a valid CAS Registry Number.
