74907-84-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 74907-84-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,9,0 and 7 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 74907-84:
(7*7)+(6*4)+(5*9)+(4*0)+(3*7)+(2*8)+(1*4)=159
159 % 10 = 9
So 74907-84-9 is a valid CAS Registry Number.
