1131147-67-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1131147-67-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,3,1,1,4 and 7 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1131147-67:
(9*1)+(8*1)+(7*3)+(6*1)+(5*1)+(4*4)+(3*7)+(2*6)+(1*7)=105
105 % 10 = 5
So 1131147-67-5 is a valid CAS Registry Number.
