127074-71-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 127074-71-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,7,0,7 and 4 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 127074-71:
(8*1)+(7*2)+(6*7)+(5*0)+(4*7)+(3*4)+(2*7)+(1*1)=119
119 % 10 = 9
So 127074-71-9 is a valid CAS Registry Number.
