Check Digit Verification of cas no
The CAS Registry Mumber 129354-67-2 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, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 129354-67:
(8*1)+(7*2)+(6*9)+(5*3)+(4*5)+(3*4)+(2*6)+(1*7)=142
142 % 10 = 2
So 129354-67-2 is a valid CAS Registry Number.
