116703-46-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 116703-46-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,6,7,0 and 3 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 116703-46:
(8*1)+(7*1)+(6*6)+(5*7)+(4*0)+(3*3)+(2*4)+(1*6)=109
109 % 10 = 9
So 116703-46-9 is a valid CAS Registry Number.
