1193725-46-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1193725-46-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,9,3,7,2 and 5 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1193725-46:
(9*1)+(8*1)+(7*9)+(6*3)+(5*7)+(4*2)+(3*5)+(2*4)+(1*6)=170
170 % 10 = 0
So 1193725-46-0 is a valid CAS Registry Number.
