127222-91-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 127222-91-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,7,2,2 and 2 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 127222-91:
(8*1)+(7*2)+(6*7)+(5*2)+(4*2)+(3*2)+(2*9)+(1*1)=107
107 % 10 = 7
So 127222-91-7 is a valid CAS Registry Number.
