263402-36-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 263402-36-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,6,3,4,0 and 2 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 263402-36:
(8*2)+(7*6)+(6*3)+(5*4)+(4*0)+(3*2)+(2*3)+(1*6)=114
114 % 10 = 4
So 263402-36-4 is a valid CAS Registry Number.
