258355-40-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 258355-40-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,8,3,5 and 5 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 258355-40:
(8*2)+(7*5)+(6*8)+(5*3)+(4*5)+(3*5)+(2*4)+(1*0)=157
157 % 10 = 7
So 258355-40-7 is a valid CAS Registry Number.
