71990-00-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 71990-00-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,1,9,9 and 0 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 71990-00:
(7*7)+(6*1)+(5*9)+(4*9)+(3*0)+(2*0)+(1*0)=136
136 % 10 = 6
So 71990-00-6 is a valid CAS Registry Number.
