1158357-45-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1158357-45-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,5,8,3,5 and 7 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1158357-45:
(9*1)+(8*1)+(7*5)+(6*8)+(5*3)+(4*5)+(3*7)+(2*4)+(1*5)=169
169 % 10 = 9
So 1158357-45-9 is a valid CAS Registry Number.
