681263-98-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 681263-98-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,8,1,2,6 and 3 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 681263-98:
(8*6)+(7*8)+(6*1)+(5*2)+(4*6)+(3*3)+(2*9)+(1*8)=179
179 % 10 = 9
So 681263-98-9 is a valid CAS Registry Number.
