Check Digit Verification of cas no
The CAS Registry Mumber 83159-27-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,3,1,5 and 9 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 83159-27:
(7*8)+(6*3)+(5*1)+(4*5)+(3*9)+(2*2)+(1*7)=137
137 % 10 = 7
So 83159-27-7 is a valid CAS Registry Number.
