1367458-40-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1367458-40-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,6,7,4,5 and 8 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1367458-40:
(9*1)+(8*3)+(7*6)+(6*7)+(5*4)+(4*5)+(3*8)+(2*4)+(1*0)=189
189 % 10 = 9
So 1367458-40-9 is a valid CAS Registry Number.
