116830-93-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 116830-93-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,6,8,3 and 0 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 116830-93:
(8*1)+(7*1)+(6*6)+(5*8)+(4*3)+(3*0)+(2*9)+(1*3)=124
124 % 10 = 4
So 116830-93-4 is a valid CAS Registry Number.
