159983-54-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 159983-54-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,9,9,8 and 3 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 159983-54:
(8*1)+(7*5)+(6*9)+(5*9)+(4*8)+(3*3)+(2*5)+(1*4)=197
197 % 10 = 7
So 159983-54-7 is a valid CAS Registry Number.
