141207-34-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 141207-34-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,1,2,0 and 7 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 141207-34:
(8*1)+(7*4)+(6*1)+(5*2)+(4*0)+(3*7)+(2*3)+(1*4)=83
83 % 10 = 3
So 141207-34-3 is a valid CAS Registry Number.
