Check Digit Verification of cas no
The CAS Registry Mumber 101976-25-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,1,9,7 and 6 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 101976-25:
(8*1)+(7*0)+(6*1)+(5*9)+(4*7)+(3*6)+(2*2)+(1*5)=114
114 % 10 = 4
So 101976-25-4 is a valid CAS Registry Number.
