80954-12-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 80954-12-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,0,9,5 and 4 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 80954-12:
(7*8)+(6*0)+(5*9)+(4*5)+(3*4)+(2*1)+(1*2)=137
137 % 10 = 7
So 80954-12-7 is a valid CAS Registry Number.
