130256-19-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 130256-19-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,0,2,5 and 6 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 130256-19:
(8*1)+(7*3)+(6*0)+(5*2)+(4*5)+(3*6)+(2*1)+(1*9)=88
88 % 10 = 8
So 130256-19-8 is a valid CAS Registry Number.
