1421005-88-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1421005-88-0 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, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1421005-88:
(9*1)+(8*4)+(7*2)+(6*1)+(5*0)+(4*0)+(3*5)+(2*8)+(1*8)=100
100 % 10 = 0
So 1421005-88-0 is a valid CAS Registry Number.
