131136-52-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 131136-52-2 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, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 131136-52:
(8*1)+(7*3)+(6*1)+(5*1)+(4*3)+(3*6)+(2*5)+(1*2)=82
82 % 10 = 2
So 131136-52-2 is a valid CAS Registry Number.
