127091-55-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 127091-55-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,7,0,9 and 1 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 127091-55:
(8*1)+(7*2)+(6*7)+(5*0)+(4*9)+(3*1)+(2*5)+(1*5)=118
118 % 10 = 8
So 127091-55-8 is a valid CAS Registry Number.
