918138-93-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 918138-93-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,1,8,1,3 and 8 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 918138-93:
(8*9)+(7*1)+(6*8)+(5*1)+(4*3)+(3*8)+(2*9)+(1*3)=189
189 % 10 = 9
So 918138-93-9 is a valid CAS Registry Number.
