119837-59-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 119837-59-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,9,8,3 and 7 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 119837-59:
(8*1)+(7*1)+(6*9)+(5*8)+(4*3)+(3*7)+(2*5)+(1*9)=161
161 % 10 = 1
So 119837-59-1 is a valid CAS Registry Number.
