79309-29-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 79309-29-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,9,3,0 and 9 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 79309-29:
(7*7)+(6*9)+(5*3)+(4*0)+(3*9)+(2*2)+(1*9)=158
158 % 10 = 8
So 79309-29-8 is a valid CAS Registry Number.
