Check Digit Verification of cas no

The CAS Registry Mumber 1283076-22-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,8,3,0,7 and 6 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1283076-22:
(9*1)+(8*2)+(7*8)+(6*3)+(5*0)+(4*7)+(3*6)+(2*2)+(1*2)=151
151 % 10 = 1
So 1283076-22-1 is a valid CAS Registry Number.

Pentaalkylmethylguanidinium methylcarbonates - Versatile precursors for the preparation of halide-free and metal-free guanidinium-based ILs

Oelkers, Benjamin,Sundermeyer, Joerg

, p. 608 - 618 (2011)

Pentaalkylmethylguanidinium methylcarbonates 6 can easily be prepared from pentaalkylguanidines 5 and dimethyl carbonate (DMC) in a sustainable solvent-free synthesis. Most of the title compounds are room temperature ionic liquids (RTILs) which provide convenient access to halide-free guanidinium-based ILs (GILs) 7via acid-base reactions and subsequent decarboxylation, similar to industrially important imidazolium methylcarbonates 1.
