173604-34-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 173604-34-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,3,6,0 and 4 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 173604-34:
(8*1)+(7*7)+(6*3)+(5*6)+(4*0)+(3*4)+(2*3)+(1*4)=127
127 % 10 = 7
So 173604-34-7 is a valid CAS Registry Number.
