131064-11-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 131064-11-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,1,0,6 and 4 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 131064-11:
(8*1)+(7*3)+(6*1)+(5*0)+(4*6)+(3*4)+(2*1)+(1*1)=74
74 % 10 = 4
So 131064-11-4 is a valid CAS Registry Number.
