158220-88-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 158220-88-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,8,2,2 and 0 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 158220-88:
(8*1)+(7*5)+(6*8)+(5*2)+(4*2)+(3*0)+(2*8)+(1*8)=133
133 % 10 = 3
So 158220-88-3 is a valid CAS Registry Number.
