Check Digit Verification of cas no
The CAS Registry Mumber 1836-22-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,8,3 and 6 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1836-22:
(6*1)+(5*8)+(4*3)+(3*6)+(2*2)+(1*2)=82
82 % 10 = 2
So 1836-22-2 is a valid CAS Registry Number.
