863649-98-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 863649-98-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,6,3,6,4 and 9 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 863649-98:
(8*8)+(7*6)+(6*3)+(5*6)+(4*4)+(3*9)+(2*9)+(1*8)=223
223 % 10 = 3
So 863649-98-3 is a valid CAS Registry Number.
