252975-27-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 252975-27-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,2,9,7 and 5 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 252975-27:
(8*2)+(7*5)+(6*2)+(5*9)+(4*7)+(3*5)+(2*2)+(1*7)=162
162 % 10 = 2
So 252975-27-2 is a valid CAS Registry Number.
