704898-67-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 704898-67-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,0,4,8,9 and 8 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 704898-67:
(8*7)+(7*0)+(6*4)+(5*8)+(4*9)+(3*8)+(2*6)+(1*7)=199
199 % 10 = 9
So 704898-67-9 is a valid CAS Registry Number.
