1153761-87-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1153761-87-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,5,3,7,6 and 1 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1153761-87:
(9*1)+(8*1)+(7*5)+(6*3)+(5*7)+(4*6)+(3*1)+(2*8)+(1*7)=155
155 % 10 = 5
So 1153761-87-5 is a valid CAS Registry Number.
