141212-80-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 141212-80-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,1,2,1 and 2 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 141212-80:
(8*1)+(7*4)+(6*1)+(5*2)+(4*1)+(3*2)+(2*8)+(1*0)=78
78 % 10 = 8
So 141212-80-8 is a valid CAS Registry Number.
