70092-38-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 70092-38-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,0,0,9 and 2 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 70092-38:
(7*7)+(6*0)+(5*0)+(4*9)+(3*2)+(2*3)+(1*8)=105
105 % 10 = 5
So 70092-38-5 is a valid CAS Registry Number.
