263388-36-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 263388-36-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,6,3,3,8 and 8 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 263388-36:
(8*2)+(7*6)+(6*3)+(5*3)+(4*8)+(3*8)+(2*3)+(1*6)=159
159 % 10 = 9
So 263388-36-9 is a valid CAS Registry Number.
