1216522-70-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1216522-70-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,1,6,5,2 and 2 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1216522-70:
(9*1)+(8*2)+(7*1)+(6*6)+(5*5)+(4*2)+(3*2)+(2*7)+(1*0)=121
121 % 10 = 1
So 1216522-70-1 is a valid CAS Registry Number.
