1338807-93-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1338807-93-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,3,8,8,0 and 7 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1338807-93:
(9*1)+(8*3)+(7*3)+(6*8)+(5*8)+(4*0)+(3*7)+(2*9)+(1*3)=184
184 % 10 = 4
So 1338807-93-4 is a valid CAS Registry Number.
