131013-27-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 131013-27-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,1,0,1 and 3 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 131013-27:
(8*1)+(7*3)+(6*1)+(5*0)+(4*1)+(3*3)+(2*2)+(1*7)=59
59 % 10 = 9
So 131013-27-9 is a valid CAS Registry Number.
