131933-90-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 131933-90-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,1,9,3 and 3 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 131933-90:
(8*1)+(7*3)+(6*1)+(5*9)+(4*3)+(3*3)+(2*9)+(1*0)=119
119 % 10 = 9
So 131933-90-9 is a valid CAS Registry Number.
