139723-70-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 139723-70-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,7,2 and 3 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 139723-70:
(8*1)+(7*3)+(6*9)+(5*7)+(4*2)+(3*3)+(2*7)+(1*0)=149
149 % 10 = 9
So 139723-70-9 is a valid CAS Registry Number.
