92831-91-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 92831-91-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,2,8,3 and 1 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 92831-91:
(7*9)+(6*2)+(5*8)+(4*3)+(3*1)+(2*9)+(1*1)=149
149 % 10 = 9
So 92831-91-9 is a valid CAS Registry Number.
