329703-93-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 329703-93-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,2,9,7,0 and 3 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 329703-93:
(8*3)+(7*2)+(6*9)+(5*7)+(4*0)+(3*3)+(2*9)+(1*3)=157
157 % 10 = 7
So 329703-93-7 is a valid CAS Registry Number.
