129052-45-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 129052-45-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,0,5 and 2 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 129052-45:
(8*1)+(7*2)+(6*9)+(5*0)+(4*5)+(3*2)+(2*4)+(1*5)=115
115 % 10 = 5
So 129052-45-5 is a valid CAS Registry Number.
