98949-90-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 98949-90-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,8,9,4 and 9 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 98949-90:
(7*9)+(6*8)+(5*9)+(4*4)+(3*9)+(2*9)+(1*0)=217
217 % 10 = 7
So 98949-90-7 is a valid CAS Registry Number.
