1178-12-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1178-12-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,1,7 and 8 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1178-12:
(6*1)+(5*1)+(4*7)+(3*8)+(2*1)+(1*2)=67
67 % 10 = 7
So 1178-12-7 is a valid CAS Registry Number.
