127239-27-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 127239-27-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,7,2,3 and 9 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 127239-27:
(8*1)+(7*2)+(6*7)+(5*2)+(4*3)+(3*9)+(2*2)+(1*7)=124
124 % 10 = 4
So 127239-27-4 is a valid CAS Registry Number.
