1329805-58-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1329805-58-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,2,9,8,0 and 5 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1329805-58:
(9*1)+(8*3)+(7*2)+(6*9)+(5*8)+(4*0)+(3*5)+(2*5)+(1*8)=174
174 % 10 = 4
So 1329805-58-4 is a valid CAS Registry Number.
