172796-98-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 172796-98-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,2,7,9 and 6 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 172796-98:
(8*1)+(7*7)+(6*2)+(5*7)+(4*9)+(3*6)+(2*9)+(1*8)=184
184 % 10 = 4
So 172796-98-4 is a valid CAS Registry Number.
