30992-84-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 30992-84-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,0,9,9 and 2 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 30992-84:
(7*3)+(6*0)+(5*9)+(4*9)+(3*2)+(2*8)+(1*4)=128
128 % 10 = 8
So 30992-84-8 is a valid CAS Registry Number.
