131563-99-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 131563-99-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,1,5,6 and 3 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 131563-99:
(8*1)+(7*3)+(6*1)+(5*5)+(4*6)+(3*3)+(2*9)+(1*9)=120
120 % 10 = 0
So 131563-99-0 is a valid CAS Registry Number.
