127745-69-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 127745-69-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,7,7,4 and 5 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 127745-69:
(8*1)+(7*2)+(6*7)+(5*7)+(4*4)+(3*5)+(2*6)+(1*9)=151
151 % 10 = 1
So 127745-69-1 is a valid CAS Registry Number.
