31925-11-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 31925-11-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,1,9,2 and 5 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 31925-11:
(7*3)+(6*1)+(5*9)+(4*2)+(3*5)+(2*1)+(1*1)=98
98 % 10 = 8
So 31925-11-8 is a valid CAS Registry Number.
