1337568-89-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1337568-89-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,3,7,5,6 and 8 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1337568-89:
(9*1)+(8*3)+(7*3)+(6*7)+(5*5)+(4*6)+(3*8)+(2*8)+(1*9)=194
194 % 10 = 4
So 1337568-89-4 is a valid CAS Registry Number.
