129354-76-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 129354-76-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,3,5 and 4 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 129354-76:
(8*1)+(7*2)+(6*9)+(5*3)+(4*5)+(3*4)+(2*7)+(1*6)=143
143 % 10 = 3
So 129354-76-3 is a valid CAS Registry Number.
