1421845-89-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1421845-89-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,2,1,8,4 and 5 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1421845-89:
(9*1)+(8*4)+(7*2)+(6*1)+(5*8)+(4*4)+(3*5)+(2*8)+(1*9)=157
157 % 10 = 7
So 1421845-89-7 is a valid CAS Registry Number.
