129885-80-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 129885-80-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,8,8 and 5 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 129885-80:
(8*1)+(7*2)+(6*9)+(5*8)+(4*8)+(3*5)+(2*8)+(1*0)=179
179 % 10 = 9
So 129885-80-9 is a valid CAS Registry Number.
