1161299-55-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1161299-55-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,6,1,2,9 and 9 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1161299-55:
(9*1)+(8*1)+(7*6)+(6*1)+(5*2)+(4*9)+(3*9)+(2*5)+(1*5)=153
153 % 10 = 3
So 1161299-55-3 is a valid CAS Registry Number.
