Check Digit Verification of cas no
The CAS Registry Mumber 841211-59-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,4,1,2,1 and 1 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 841211-59:
(8*8)+(7*4)+(6*1)+(5*2)+(4*1)+(3*1)+(2*5)+(1*9)=134
134 % 10 = 4
So 841211-59-4 is a valid CAS Registry Number.
