19355-57-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 19355-57-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,3,5 and 5 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 19355-57:
(7*1)+(6*9)+(5*3)+(4*5)+(3*5)+(2*5)+(1*7)=128
128 % 10 = 8
So 19355-57-8 is a valid CAS Registry Number.
