1145778-26-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1145778-26-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,4,5,7,7 and 8 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1145778-26:
(9*1)+(8*1)+(7*4)+(6*5)+(5*7)+(4*7)+(3*8)+(2*2)+(1*6)=172
172 % 10 = 2
So 1145778-26-2 is a valid CAS Registry Number.
