807331-98-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 807331-98-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,0,7,3,3 and 1 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 807331-98:
(8*8)+(7*0)+(6*7)+(5*3)+(4*3)+(3*1)+(2*9)+(1*8)=162
162 % 10 = 2
So 807331-98-2 is a valid CAS Registry Number.
