1375467-89-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1375467-89-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,7,5,4,6 and 7 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1375467-89:
(9*1)+(8*3)+(7*7)+(6*5)+(5*4)+(4*6)+(3*7)+(2*8)+(1*9)=202
202 % 10 = 2
So 1375467-89-2 is a valid CAS Registry Number.
