CAS DataBase Reference: 4,7-Methano-1H-indene, 3a,4,7,7a-tetrahydro-, polymer with ethenylbenzene, ethenylmethylbenzene, 1H-indene and (1-methylethenyl)benzene(CAS DataBase Reference)
NIST Chemistry Reference: 4,7-Methano-1H-indene, 3a,4,7,7a-tetrahydro-, polymer with ethenylbenzene, ethenylmethylbenzene, 1H-indene and (1-methylethenyl)benzene(68240-01-7)
EPA Substance Registry System: 4,7-Methano-1H-indene, 3a,4,7,7a-tetrahydro-, polymer with ethenylbenzene, ethenylmethylbenzene, 1H-indene and (1-methylethenyl)benzene(68240-01-7)
The CAS Registry Mumber 68240-01-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,8,2,4 and 0 respectively; the second part has 2 digits, 0 and 1 respectively. Calculate Digit Verification of CAS Registry Number 68240-01: (7*6)+(6*8)+(5*2)+(4*4)+(3*0)+(2*0)+(1*1)=117 117 % 10 = 7 So 68240-01-7 is a valid CAS Registry Number.
