58216-30-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 58216-30-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,8,2,1 and 6 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 58216-30:
(7*5)+(6*8)+(5*2)+(4*1)+(3*6)+(2*3)+(1*0)=121
121 % 10 = 1
So 58216-30-1 is a valid CAS Registry Number.
