Check Digit Verification of cas no
The CAS Registry Mumber 1421005-78-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,2,1,0,0 and 5 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1421005-78:
(9*1)+(8*4)+(7*2)+(6*1)+(5*0)+(4*0)+(3*5)+(2*7)+(1*8)=98
98 % 10 = 8
So 1421005-78-8 is a valid CAS Registry Number.
