1338567-49-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1338567-49-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,3,8,5,6 and 7 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1338567-49:
(9*1)+(8*3)+(7*3)+(6*8)+(5*5)+(4*6)+(3*7)+(2*4)+(1*9)=189
189 % 10 = 9
So 1338567-49-9 is a valid CAS Registry Number.
