1177441-29-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1177441-29-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,7,7,4,4 and 1 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1177441-29:
(9*1)+(8*1)+(7*7)+(6*7)+(5*4)+(4*4)+(3*1)+(2*2)+(1*9)=160
160 % 10 = 0
So 1177441-29-0 is a valid CAS Registry Number.
