117902-29-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 117902-29-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,7,9,0 and 2 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 117902-29:
(8*1)+(7*1)+(6*7)+(5*9)+(4*0)+(3*2)+(2*2)+(1*9)=121
121 % 10 = 1
So 117902-29-1 is a valid CAS Registry Number.
