116053-67-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 116053-67-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,6,0,5 and 3 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 116053-67:
(8*1)+(7*1)+(6*6)+(5*0)+(4*5)+(3*3)+(2*6)+(1*7)=99
99 % 10 = 9
So 116053-67-9 is a valid CAS Registry Number.
