1192160-29-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1192160-29-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,9,2,1,6 and 0 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1192160-29:
(9*1)+(8*1)+(7*9)+(6*2)+(5*1)+(4*6)+(3*0)+(2*2)+(1*9)=134
134 % 10 = 4
So 1192160-29-4 is a valid CAS Registry Number.
