130042-86-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 130042-86-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,0,0,4 and 2 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 130042-86:
(8*1)+(7*3)+(6*0)+(5*0)+(4*4)+(3*2)+(2*8)+(1*6)=73
73 % 10 = 3
So 130042-86-3 is a valid CAS Registry Number.
