1263477-18-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1263477-18-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,3,4,7 and 7 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1263477-18:
(9*1)+(8*2)+(7*6)+(6*3)+(5*4)+(4*7)+(3*7)+(2*1)+(1*8)=164
164 % 10 = 4
So 1263477-18-4 is a valid CAS Registry Number.
