122947-29-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 122947-29-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,2,9,4 and 7 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 122947-29:
(8*1)+(7*2)+(6*2)+(5*9)+(4*4)+(3*7)+(2*2)+(1*9)=129
129 % 10 = 9
So 122947-29-9 is a valid CAS Registry Number.
