90158-33-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 90158-33-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,1,5 and 8 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 90158-33:
(7*9)+(6*0)+(5*1)+(4*5)+(3*8)+(2*3)+(1*3)=121
121 % 10 = 1
So 90158-33-1 is a valid CAS Registry Number.
