Check Digit Verification of cas no
The CAS Registry Mumber 188292-22-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,8,2,9 and 2 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 188292-22:
(8*1)+(7*8)+(6*8)+(5*2)+(4*9)+(3*2)+(2*2)+(1*2)=170
170 % 10 = 0
So 188292-22-0 is a valid CAS Registry Number.
