90211-70-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 90211-70-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,2,1 and 1 respectively; the second part has 2 digits, 7 and 0 respectively.Calculate Digit Verification of CAS Registry Number 90211-70:
(7*9)+(6*0)+(5*2)+(4*1)+(3*1)+(2*7)+(1*0)=94
94 % 10 = 4
So 90211-70-4 is a valid CAS Registry Number.
