129708-92-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 129708-92-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,7,0 and 8 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 129708-92:
(8*1)+(7*2)+(6*9)+(5*7)+(4*0)+(3*8)+(2*9)+(1*2)=155
155 % 10 = 5
So 129708-92-5 is a valid CAS Registry Number.
