131598-61-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 131598-61-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,1,5,9 and 8 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 131598-61:
(8*1)+(7*3)+(6*1)+(5*5)+(4*9)+(3*8)+(2*6)+(1*1)=133
133 % 10 = 3
So 131598-61-3 is a valid CAS Registry Number.
