127975-42-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 127975-42-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,7,9,7 and 5 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 127975-42:
(8*1)+(7*2)+(6*7)+(5*9)+(4*7)+(3*5)+(2*4)+(1*2)=162
162 % 10 = 2
So 127975-42-2 is a valid CAS Registry Number.
