263908-29-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 263908-29-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,6,3,9,0 and 8 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 263908-29:
(8*2)+(7*6)+(6*3)+(5*9)+(4*0)+(3*8)+(2*2)+(1*9)=158
158 % 10 = 8
So 263908-29-8 is a valid CAS Registry Number.
