129223-47-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 129223-47-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,2,2 and 3 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 129223-47:
(8*1)+(7*2)+(6*9)+(5*2)+(4*2)+(3*3)+(2*4)+(1*7)=118
118 % 10 = 8
So 129223-47-8 is a valid CAS Registry Number.
