131136-67-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 131136-67-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,1,1,3 and 6 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 131136-67:
(8*1)+(7*3)+(6*1)+(5*1)+(4*3)+(3*6)+(2*6)+(1*7)=89
89 % 10 = 9
So 131136-67-9 is a valid CAS Registry Number.
