131497-69-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 131497-69-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,1,4,9 and 7 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 131497-69:
(8*1)+(7*3)+(6*1)+(5*4)+(4*9)+(3*7)+(2*6)+(1*9)=133
133 % 10 = 3
So 131497-69-3 is a valid CAS Registry Number.
