114042-92-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 114042-92-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,4,0,4 and 2 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 114042-92:
(8*1)+(7*1)+(6*4)+(5*0)+(4*4)+(3*2)+(2*9)+(1*2)=81
81 % 10 = 1
So 114042-92-1 is a valid CAS Registry Number.
