127841-06-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 127841-06-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,7,8,4 and 1 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 127841-06:
(8*1)+(7*2)+(6*7)+(5*8)+(4*4)+(3*1)+(2*0)+(1*6)=129
129 % 10 = 9
So 127841-06-9 is a valid CAS Registry Number.
