1174715-26-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1174715-26-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,7,4,7,1 and 5 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1174715-26:
(9*1)+(8*1)+(7*7)+(6*4)+(5*7)+(4*1)+(3*5)+(2*2)+(1*6)=154
154 % 10 = 4
So 1174715-26-4 is a valid CAS Registry Number.
