127941-22-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 127941-22-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,7,9,4 and 1 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 127941-22:
(8*1)+(7*2)+(6*7)+(5*9)+(4*4)+(3*1)+(2*2)+(1*2)=134
134 % 10 = 4
So 127941-22-4 is a valid CAS Registry Number.
