Check Digit Verification of cas no
The CAS Registry Mumber 1427005-91-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,2,7,0,0 and 5 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1427005-91:
(9*1)+(8*4)+(7*2)+(6*7)+(5*0)+(4*0)+(3*5)+(2*9)+(1*1)=131
131 % 10 = 1
So 1427005-91-1 is a valid CAS Registry Number.
