127090-99-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 127090-99-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,7,0,9 and 0 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 127090-99:
(8*1)+(7*2)+(6*7)+(5*0)+(4*9)+(3*0)+(2*9)+(1*9)=127
127 % 10 = 7
So 127090-99-7 is a valid CAS Registry Number.
