1621538-58-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1621538-58-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,2,1,5,3 and 8 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1621538-58:
(9*1)+(8*6)+(7*2)+(6*1)+(5*5)+(4*3)+(3*8)+(2*5)+(1*8)=156
156 % 10 = 6
So 1621538-58-6 is a valid CAS Registry Number.
