131604-86-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 131604-86-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,1,6,0 and 4 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 131604-86:
(8*1)+(7*3)+(6*1)+(5*6)+(4*0)+(3*4)+(2*8)+(1*6)=99
99 % 10 = 9
So 131604-86-9 is a valid CAS Registry Number.
