127997-03-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 127997-03-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,7,9,9 and 7 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 127997-03:
(8*1)+(7*2)+(6*7)+(5*9)+(4*9)+(3*7)+(2*0)+(1*3)=169
169 % 10 = 9
So 127997-03-9 is a valid CAS Registry Number.
