Check Digit Verification of cas no
The CAS Registry Mumber 141948-39-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,1,9,4 and 8 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 141948-39:
(8*1)+(7*4)+(6*1)+(5*9)+(4*4)+(3*8)+(2*3)+(1*9)=142
142 % 10 = 2
So 141948-39-2 is a valid CAS Registry Number.
